CONJUGATES OF A CELL-BINDING MOLECULE WITH CAMPTOTHECIN ANALOGSFIELD OF THE INVENTION
[0001] This invention relates to conjugates of a camptothecin analog with a cell-surface receptor-binding molecule for targeted therapy. The invention also relates to use of compositions comprising a conjugate of the camptothecin analog to a cell-binding molecule for targeted treatment of cancer, autoimmune disease, and infectious disease.BACKGROUND OF THE INVENTION
[0002] Targeted cancer strategies aim to minimize or overcome such side effects by better targeting the tumor and avoiding healthy tissues. One of the strategies is antibody-drug conjugate (ADC) which combines the precision of the antibody towards the tumor with the high potent cytotoxicity of the drug in question (the payload) through a conditionally stable linker, thereby increasing the local concentration of the latter several-folds than the health tissues. The intensive research and the huge funding by the pharmaceutical industries on ADCs during the past four decades have led to USFDA approval of 8 ADCs, named Mylotarg (gemtuzumab ozogamicin) , Adcetris (brentuximab vedotin) , Kadcyla (ado-trastuzumab emtansine) , Besponsa (inotuzumab ozogamicin) , Polivy (polatuzumab vedotin-piiq) , Enhertu (fam-trastuzumab deruxtecan-nxki) , Padcev (enfortumab vedotin-ejfv) , Trodelvy (sacituzumab govitecan) and over 100 ADC drugs are now in the clinic development (Chau, C.H. et al, Lancet. 2019, 394, 793-804) .
[0003] It has been known that the payload-linker component in the ADC complexes modality critically contribute to ADC homogeneity, circulation stability, pharmacokinetic profiles, tolerability, and overall treatment efficacy (Zhao, R.Y. et al (2011) J. Med. Chem. 54, 3606; Acchionea, M. et al (2012) mAbs, 4, 362; Doronina, S. et al, (2006) Bioconjug Chem, 17, 114; Hamann, P. et al. (2005) Bioconjug Chem. 16, 346) . Despite extensive study to improve these parameters for the next generation of ADCs, most payloads used to date are still narrowly selected from maytansins (DM1 and DM4) , auruistatins (MMAE and MMAF) , calicheamicins, Pyrrolo [2, 1-c] [1, 4] benzodiazepine (PBD) dimers, camptothecins, duocarmysins and tubulysins (Leung, D., et al, Antibodies (Basel) . 2020, 9: E2. doi: 10.3390 / antib9010002; Khongorzul, P., et al, Mol Cancer Res. 2020, 18: 3-19. doi: 10.1158 / 1541-7786. MCR-19-0582; Chau, C.H., et al, Lancet. 2019, 394: 793-804. doi: 10.1016 / S0140-6736 (19) 31774-X) .
[0004] Among these payloads, the camptothecins (CPTs) have proved promising choice with a wider therapeutic index (TI) than many other payloads for ADC construction as two of their ADC compounds, Enhertu (fam-trastuzumab deruxtecan-nxki, or DS-8201a) and Sacituzumab govitecan (IMMU-132 or hRS7-SN-38) have demonstrated significant clinical benefits (PFS and OS) for solid tumors in many clinical trials (Pondé, N., et al, Curr Treat Options Oncol. 2019 Apr 1; 20 (5) : 37. doi: 10.1007 / s11864-019-0633-6; Kaplon, H., et al, MAbs. 2020, 12 (1) : 1703531, 10.1080 / 19420862.2019.1703531) . Camptothecin (CPT) is a potent antitumor antibiotic isolated in 1958 from extracts of Camptotheca acuminata, a tree native to China wherein the plant has been extensively used in traditional Chinese medicine for hundreds of years. Camptothecin can cause a cell death through interacting with DNA enzyme topoisomerase I and then accumulating reversible enzyme–camptothecin–DNA ternary complexes (Wu Du, Tetrahedron 59 (2003) 8649–8687) . Many of camptothecin analogs have been disclosed during the past five decades as shown below:
[0005] camptothecin, 20-deoxycamptothecin, 10-methoxycamptothecin, 9-methoxycamptothecin, 10-hydroxycamptothecin, 19-dehydrocamptothecin, topotecan, irinotecan (camtosar) , Simmitecan, SN-38, Silatecan, Cositecan (Karenitecin) , Exatecan, Lurtotecan, GI-149893, 9-Glycineamidocamptothecin HCl (MLS000756803) , 10, 11-Methylenedioxycamptothecin (Mdo-CPT) ; Gimatecan, Belotecan, Rubitecan or IDEC-132 analog, Elomotecan (BN-80927) , 9-aminocamptothecin (9-AC) , 10-aminocamptothecin (10-AC) , 11-Cyanocamptothecin (NSC609951) , 7-Acetyl-Camptothecin (SCHEMBL6851483) , 7-hydroxymethylcamptothecin, 10-Amino-11-hydroxy-camptothecin (BDBM50285230) , Diflomotecan, Camptothecin-20-O-propionate (CZ-48) , Camptothecin chloroacetate (DL5FFZ93W4) , Camptothecin lysinate (NSC610457) , Sacituzumab govitecan (Immu-132) (mAb here is a monoclonal Trop2 antibody) , trastuzumab deruxtecan (DS-8201a) ( (mAb here is a Her2 antibody, trastuzumab) , Jeffrey S., et al US2019 / 0343828, (Li, W., et al, ACS Med Chem Lett. 2019, 10 (10) : 1386–1392)
[0006] Camptothecin (CPT) and most of its analogs are extremely insoluble in physiological buffer and high adverse drug reaction in the preliminary clinical trials since 1970s. Camptothecin ADC cause their ADC conjugates aggregation up to 80% (Burke, P., et al Bioconjugate Chem. 2009, 20, 6, 1242-1250) that can limit the successes of the scale-up manufacturing production and the attainments of clinical trials due to systemic side-effects resulting from the aggregation. So far US FDA only approved three water-soluble CPT analogues, topotecan, irinotecan, and belotecan that are used in cancer chemotherapy (Palakurthi, S., Expert Opin Drug Deliv. 2015; 12 (12) : 1911-21; Shang, X.F. et al, Med Res Rev. 2018, 38 (3) : 775-828) and one water-soluble CPT analog ADC, Enhertu (fam-trastuzumab deruxtecan-nxki, or DS-8201a) as targeted immunotherapy for Her2 solid tumor (Modi S, et al, N Engl J Med. 2020, 382 (7) : 610-621. doi: 10.1056 / NEJMoa1914510; Keam, S.J., Drugs. 2020 Apr; 80 (5) : 501-508. doi: 10.1007 / s40265-020-01281-4) . We have worked on water-soluble CPT analog ADC for quite a while and applied hydrophilic side-chain linkers to the CPT analog ADCs (see PCT / CN2019 / 092614) to widen the therapeutic windows of the ADCs. Here this application disclosed a water-soluble CPT analog ADC wherein C-10 position of the CPT analog that is linked to O or NH is critical for water solubility and C-11 position linked to an electron withdrawing group or a bulking group to maintain highly potent cytotoxity as in comparison to natural CPTs.

Natural amino acids are those encoded by the genetic code, which are alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tyrosine. tryptophan and valine. The unnatural amino acids are derived forms of proteinogenic amino acids. Examples include hydroxyproline, lanthionine, 2-aminoisobutyric acid, dehydroalanine, gamma-aminobutyric acid (the neurotransmitter) , ornithine, citrulline, beta alanine (3-aminopropanoic acid) , gamma-carboxyglutamate, selenocysteine (present in many noneukaryotes as well as most eukaryotes, but not coded directly by DNA) , pyrrolysine (found only in some archaea and one bacterium) , N-formylmethionine (which is often the initial amino acid of proteins in bacteria, mitochondria, and chloroplasts) , 5-hydroxytryptophan, L-dihydroxyphenylalanine, triiodothyronine, L-3, 4-dihydroxyphenylalanine (DOPA) , and O-phosphoserine. The term amino acid also includes amino acid analogs and mimetics. Analogs are compounds having the same general H2N (R) CHCO2H structure of a natural amino acid, except that the R group is not one found among the natural amino acids. Examples of analogs include homoserine, norleucine, 3-aminopropanoic acid, 4-aminobutanoic acid, 5-aminopentanoic acid, 6-aminohexanoic acid, 7-aminoheptanoic acid, methionine-sulfoxide, and methionine methyl sulfonium. Preferably, an amino acid mimetic is a compound that has a structure different from the general chemical structure of an alpha-amino acid but functions in a manner similar to one. The term "unnatural amino acid" is intended to represent the "D" stereochemical form, the natural amino acids being of the "L" form. When 1~8 amino acids are used in this patent application, amino acid sequence is then preferably a cleavage recognition sequence for a protease. Many cleavage recognition sequences are known in the art. See, e.g., Matayoshi et al. Science 247: 954 (1990) ; Dunn et al. Meth. Enzymol. 241: 254 (1994) ; Seidah et al. Meth. Enzymol. 244: 175 (1994) ; Thornberry, Meth. Enzymol. 244: 615 (1994) ; Weber et al. Meth. Enzymol. 244: 595 (1994) ; Smith et al. Meth. Enzymol. 244: 412 (1994) ; and Bouvier et al. Meth.

It is used herein as a monosaccharide, disaccharide, polyols, or oligosaccharides containing 3-6 sugar units.
[0083] The term "antibody, " as used herein, refers to a full-length immunoglobulin molecule or an immunologically active portion of a full-length immunoglobulin molecule, i.e., a molecule that contains an antigen binding site that immunospecifically binds an antigen of a target of interest or part thereof, such targets including but not limited to, cancer cell or cells that produce auto-immune antibodies associated with an autoimmune disease. The immunoglobulin disclosed herein can be of any type (e.g. IgG, IgE, IgM, IgD, IgA and IgY) , class (e.g., IgG1, IgG2, IgG3, IgG4, IgA1 and IgA2) or subclass of immunoglobulin molecule. The immunoglobulins can be derived from any species. Preferably, however, the immunoglobulin is of human, murine, or rabbit origin. Antibodies useful in the invention are preferably monoclonal, and include, but are not limited to, polyclonal, monoclonal, bispecific, human, humanized or chimeric antibodies, single chain antibodies, Fv, Fab fragments, F (ab') fragments, F (ab') 2 fragments, fragments produced by a Fab expression library, anti-idiotypic (anti-Id) antibodies, CDR's, and epitope-binding fragments of any of the above which immunospecifically bind to cancer cell antigens, viral antigens or microbial antigens.
[0084] The term "monoclonal antibody" as used herein refers to an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical except for possible naturally-occurring mutations that may be present in minor amounts. Monoclonal antibodies are highly specific, being directed against a single antigenic site. The modifier "monoclonal" indicates the character of the antibody as being obtained from a substantially homogeneous population of antibodies, and is not to be construed as requiring production of the antibody by any particular method.
[0085] An "intact antibody" is one which comprises an antigen-binding variable region as well as a light chain constant domain (CL) and heavy chain constant domains, CH1, CH2, CH3 and CH4, as appropriate for the antibody class. The constant domains may be native sequence constant domains (e.g., human native sequence constant domains) or amino acid sequence variant thereof.
[0086] An "antibody fragment" comprises a portion of an intact antibody, comprising the antigen-binding or variable region thereof. Examples of antibody fragments include Fab, Fab', F (ab') . sub. 2, and Fv fragments, diabodies, triabodies, tetrabodies, linear antibodies, single-chain antibody molecules, scFv, scFv-Fc, multispecific antibody fragments formed from antibody fragment (s) , a fragment (s) produced by a Fab expression library, or an epitope-binding fragments of any of the above which immunospecifically bind to a target antigen (e.g., a cancer cell antigen, a viral antigen or a microbial antigen) .
[0087] An "antigen" is an entity to which an antibody specifically binds.
[0088] The terms "specific binding" and "specifically binds" mean that the antibody or antibody derivative will bind, in a highly selective manner, with its corresponding epitope of a target antigen and not with the multitude of other antigens. Typically, the antibody or antibody derivative binds with an affinity of at least about 1 x 10-7 M, and preferably 10-8 M to 10-9 M, 10-10 M, 10-11 M, or 10-12 M and binds to the predetermined antigen with an affinity that is at least two-fold greater than its affinity for binding to a non-specific antigen (e.g., BSA, casein) other than the predetermined antigen or a closely-related antigen.
[0089] An “enantiomer” , also known as an “optical isomer” , is one of two stereoisomers that are mirror images of each other that are non-superposable (not identical) , much as one's left and right hands are the same except for being reversed along one axis (the hands cannot be made to appear identical simply by reorientation) . A single chiral atom or similar structural feature in a compound causes that compound to have two possible structures which are non-superposable, each a mirror image of the other. The presence of multiple chiral features in a given compound increases the number of geometric forms possible, though there may be some perfect-mirror-image pairs. Enantiopure compounds refer to samples having, within the limits of detection, molecules of only one chirality. When present in a symmetric environment, enantiomers have identical chemical and physical properties except for their ability to rotate plane-polarized light (+ / -) by equal amounts but in opposite directions (although the polarized light can be considered an asymmetric medium) . They are sometimes called optical isomers for this reason. A mixture of equal parts of an optically active isomer and its enantiomer is termed racemic and has zero net rotation of plane-polarized light because the positive rotation of each (+) form is exactly counteracted by the negative rotation of a (-) one. Enantiomer members often have different chemical reactions with other enantiomer substances. Since many biological molecules are enantiomers, there is sometimes a marked difference in the effects of two enantiomers on biological organisms. In drugs, for example, often only one of a drug's enantiomers is responsible for the desired physiologic effects, while the other enantiomer is less active, inactive, or sometimes even productive of adverse effects. Owing to this discovery, drugs composed of only one enantiomer ( "enantiopure" ) can be developed to enhance the pharmacological efficacy and sometimes eliminate some side effects.
[0090] Isotopes are variants of a particular chemical element which differs in neutron number. All isotopes of a given element have the same number of protons in each atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively. The atomic number of carbons is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7 and 8 respectively. Hydrogen atom has three isotopes of protium (1H) , deuterium (2H) , and tritium (3H) , which deuterium has twice the mass of protium and tritium has three times the mass of protium. Isotopic substitution can be used to determine the mechanism of a chemical reaction and via the kinetic isotope effect. Isotopic substitution can be used to study how the body affects a specific xenobiotic / chemical after administration through the mechanisms of absorption and distribution, as well as the metabolic changes of the substance in the body (e.g. by metabolic enzymes such as cytochrome P450 or glucuronosyltransferase enzymes) , and the effects and routes of excretion of the metabolites of the drug. This study is called pharmacokinetics (PK) . Isotopic substitution can be used to study of the biochemical and physiologic effects of drugs. The effects can include those manifested within animals (including humans) , microorganisms, or combinations of organisms (for example, infection) . This study is called pharmacodynamics (PD) . The effects can include those manifested within animals (including humans) , microorganisms, or combinations of organisms (for example, infection) . Both together influence dosing, benefit, and adverse effects of the drug. isotopes can contain a stable (non-radioactive) or an unstable element. Isotopic substitution of a drug may have a different therapeutical efficacy of the original drug. By isotopically-labeling the presently disclosed compounds, the compounds may be useful in drug and / or substrate tissue distribution assays. Tritiated (3H) and carbon-14 (14C) labeled compounds are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (2H) can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labeled compounds presently disclosed, including pharmaceutical salts, esters, and prodrugs thereof, can be prepared by any means known in the art. Benefits may also be obtained from replacement of normally abundant 12C with 13C.

[0221] In another embodiment, the synthetic routes to produce the Camptothecin analogs and their conjugation to a cell-surface receptor binding molecules of the present invention are exampled, but not limited to, as shown in figures 1-32.
[0222] In another embodiment, the releasable linker (L) is a chain of atoms selected from C, N, O, S, Si, and P that covalently connects the cell-surface binding ligand (T) to the potent Camptothecin analogs. The linker may have a wide variety of lengths, such as in the range from about 2 to about 100 atoms. The atoms used in forming the linker may be combined in all chemically relevant ways, such as forming alkylene, alkenylene, and alkynylene, ethers, polyoxyalkylene, esters, amines, imines, polyamines, hydrazines, hydrazones, amides, ureas, semicarbazides, carbazides, alkoxyamines, alkoxylamines, urethanes, amino acids, acyloxylamines, hydroxamic acids, and many others. In addition, it is to be understood that the atoms forming the releasable linker (L) may be either saturated or unsaturated, or may be radicals, or may be cyclized upon each other to form divalent cyclic structures, including cyclo alkanes, cyclic ethers, cyclic amines, arylenes, heteroarylenes, and the like in the linker.
[0223] The term releasable linker refers to a linker that includes at least one bond that can be broken under physiological conditions, such as a pH-labile, acid-labile, base-labile, oxidatively labile, metabolically labile, biochemically labile, or enzyme-labile bond. It is appreciated that such physiological conditions resulting in bond breaking do not necessarily include a biological or metabolic process, and instead may include a standard chemical reaction, such as a hydrolysis or substitution reaction, for example, an endosome having a lower pH than cytosolic pH, and / or disulfide bond exchange reaction with a intracellular thiol, such as the amillimolar range of abundant of glutathione inside the malignant cells.
[0224] The releasable linker L of conjugates may have the formula: --Ww- (Aa) r-Vv-- wherein: --W-- is a Stretcher unit; w is 0 or 1; each --Aa-- is independently an Amino Acid unit; r is independently an integer ranging from 0 to 12; --V-- is a Spacer unit; and v is 0, 1 or 2.
[0225] The Stretcher unit (--W--) , when present, links a targeted binding molecular unit (T) to an amino acid unit (--Aa--) , or links to V when an Aa is not present. The Stretcher unit W may independently contain a self-immolative spacer, peptidyl units, a hydrazone bond, disulfides or thioether bond. In this regard a binding molecular (T) has a functional group that can form a bond with a functional group of a Stretcher. Useful functional groups that can be present on a binding molecular, either naturally or via chemical manipulation include, but are not limited to, sulfhydryl (--SH) , amino, hydroxyl, carbonyl, the anomeric hydroxyl group of a carbohydrate, and carboxyl. Preferred functional groups are sulfhydryl, carboxy and amino. Sulfhydryl groups can be generated by reduction of an intramolecular disulfide bond of a Ligand. Alternatively, sulfhydryl groups can be generated by reaction of an amino group of a lysine moiety of a binding molecular using 2-iminothiolane (Traut's reagent) or thiolactone or another sulfhydryl generating reagent, such as modifies T with a disulfide bond linker, or a thiol ester following by reduction or hydrolysis respectively.
[0226] Illustrative examples of W linked to T have the structures:
[0227] wherein R20 and R21 are selected from –C1~C9 alkylene-, -C1~C7 carbocyclo-, -O- (C1~C8 alkyl) -, -arylene-, -C1~C9 alkylene-arylene-, -arylene, -C1~C9 alkylene-, -C1~C9 alkylene- (C1~C8 carbocyclo) -, - (C3~C7 carbocyclo) -C1~C9 alkylene-, -C3~C8 heterocyclo-, -C1~C10 alkylene- (C3~C8 heterocyclo) -, - (C3~C8 heterocyclo) -C1~C9 alkylene-, - (CH2CH2O) k-, - (CH (CH3) CH2O) k-, and - (CH2CH2O) k-CH2-; k is an integer ranging from 1-20.; R’ and R” are independently H or CH3.
[0228] In another embodiment, conjugation of W to T covalently as illustrated above can be via various chemical reactions, which are typical conjugation methodologies:
[0229] Examples of the formation of amide linkages of the conjugates:
[0230]
[0231] Wherein the Stretcher unit contains a reactive site of E, which can form an amide bond with a primary or secondary amino group of a Ligand. Example of the reactive E, includes, but is not limited to, such as hydroxysuccinimidyl esters (NHS, Sulfo-NHS, etc) , 4-nitrophenyl esters, pentafluorophenyl esters, tetrafluorophenyl (includes sulfo-tetrafluorophenyl) esters, anhydrides, acid chlorides, sulfonyl chlorides, isocyanates and isothiocyanates.
[0232] Examples of thiol ether or disulfide bond linkages of the conjugates:
[0233]
[0234] wherein the Stretcher unit contains a sulfhydryl reactive site, which can form a thiol ether or disulfide bond with a thiol group which is generated by reduction of an intramolecular disulfide bond of the binding ligand T, or generated by a chemical modification on the binding ligand T as shown in the above figure.
[0235] In yet another aspect of the invention, the reactive group of the Stretcher contains a reactive site that is reactive to an aldehyde (--CHO) or a ketone (-C (=O) R) group that can be chemically modified on a binding molecular T. For example, a carbohydrate on a binding molecular T can be mildly oxidized using a reagent such as sodium periodate to generate an aldehyde or a ketone (-C (=O) R) group; or an amine on an amino acid at the N-termini of antibodies (or proteins or peptides) can react with pyridoxal 5’-phosphate (PLP) in a buffer solution to introduce ketone groups (Scheck &Francis, ACS Chem. Biol. 2007, 2, 247-251) . The resulting (--C=O) unit can be condensed with a Stretcher that contains a functionality such as a hydrazide, an oxime, a primary or secondary amine, a hydrazine, a thiosemicarbazone, a hydrazine carboxylate, and an arylhydrazide.
[0236] Examples of the conjugation of the hydrazone, or the oxime or imine linkages:
[0237]
[0238] wherein R20 and R21 are described above, R25 is an organic substituent of an amino acid.
[0239] In another aspect of the invention, the Stretchers (which may contain a spacer V and / or an amino acid) can be linked to the binding molecules (T) , followed by conjugation of a potent Camptothecin analog to the binding molecule-stretcher moiety in an aqueous buffered solution. Examples of these kinds of two-step conjugations (a drug linked to R16 is omitted here) :
[0240]
[0241]
[0242] wherein E includes, but is not limited to, such as hydroxysuccinimidyl esters (NHS, Sulfo-NHS, etc) , 4-nitrophenyl esters, pentafluorophenyl esters, tetrafluorophenyl (includes sulfo-tetrafluorophenyl) esters, anhydrides, acid chlorides, sulfonyl chlorides, isocyanates and isothiocyanates. R’ and R” are independently H or CH3; R20, R16 and Ar are defined in various embodiment throughout this inventions; R26 is H, or F, or NO2 independently; J is F, Cl, Br, I, tosylate (TsO) or mesylate (MsO) independently and wherein bears at least one Camptothecin analog / drug as shown
[0243] In another aspect of the invention, the Stretchers can be linked to a potent Camptothecin analog first, followed by conjugation of the binding molecules (T) in an aqueous pH 3 ~ 10 (preferably pH 5 ~ 8.5) buffered solution containing up to 50%of organic cosolvents. Examples of these kinds of two-step conjugations:
[0244]
[0245] wherein E includes, but is not limited to, such as hydroxysuccinimidyl esters (NHS, Sulfo-NHS, etc) , 4-nitrophenyl esters, pentafluorophenyl esters, tetrafluorophenyl (includes sulfo-tetrafluorophenyl) esters, anhydrides, acid chlorides, sulfonyl chlorides, isocyanates and isothiocyanates. R’ and R” are independently H or CH3; R16, R20 and Ar are defined in various embodiment throughout this inventions; R26 is H, or F, or NO2 independently; J is F, Cl, Br, I, tosylate (TsO) or mesylate (MsO) independently and wherein bears at least one Camptothecin analog / drug.
[0246] The Amino Acid unit (-Aa-) , when present, links the Stretcher unit to the Spacer unit if the Spacer unit is present, links the Stretcher unit to the Camptothecin analog unit if the Spacer unit is absent, and links the binding molecule (T) unit to the Camptothecin analog unit if the Stretcher unit and Spacer unit are absent. - (Aa) r-is a natural or unnatural amino acid, the same or different sequences of amino acids of dipeptide, tripeptide, tetrapeptide, pentapeptide, hexapeptide, heptapeptide, octapeptide, nonapeptide, decapeptide, undecapeptide or dodecapeptide unit, and r is an integer ranging from 0 to 12. The term amino acid as used herein refers generally to aminoalkylcarboxylate, where the alkyl radical is optionally substituted, such as with alkyl, acyl, hydroxy alkyl, sulfhydrylalkyl, aminoalkyl, carboxyalkyl, and the like, The structures of the natural and unnatural amino acids and peptides are described in the book: G.C. Barrett and D.T. Elmore, “Amino Acid and Peptide” , Cambridge University Press, 2004. In addition, amino acid refers to beta, gamma, and longer amino acids with intra chain containing methyl, benzyl, hydroxymethyl, thiomethyl, carboxyl, carboxylmethyl, guanidinopropyl, and the like. More preferably the amino acid is selected from asparagine, aspartic acid, cysteine, glycine, glutamic acid, lysine, glutamine, arginine, serine, ornithine, threonine, and the like.
[0247] The Amino Acid unit of the invention can be enzymatically cleaved by one or more enzymes, including a tumor-associated protease, to liberate the Camptothecin analog, which in one embodiment is protonated in vivo upon release to provide a Camptothecin analog.
[0248] The Spacer unit (-V-) , when present, links an Amino Acid unit to the Camptothecin analog when an Amino Acid unit is present. Alternately, the Spacer unit links the Stretcher unit to Camptothecin analog when the Amino Acid unit is absent. The Spacer unit also links to Camptothecin analog and to the binding molecule (T) when both the Amino Acid unit and Stretcher unit are absent. The spacer linkers may contain function groups that substantially increase the water solubility, biological transport, preferential renal clearance, uptake, absorption, biodistribution, and / or bioavailability of the conjugate are described herein. Spacer units are of two general types: self-immolative and non-self-immolative. A non-self-immolative Spacer unit is one in which part or all of the Spacer unit remains bound to Camptothecin analog after cleavage, particularly enzymatic, of an Amino Acid unit from the Camptothecin analog-Linker-binding molecule conjugate or the Camptothecin analog-Linker Compound. The self-immolative unit includes aromatic compounds that are electronically similar to para-aminobenzyl-carbamoyl (PAB) groups, 2-aminoimidazol-5-methanol derivatives, heterocyclic PAB analogs, beta-glucuronide, and ortho or para-aminobenzylacetals; or one of the following structures:

[0285] In the process of the conjugation, prior to conjugating with the Camptothecin analogs of this invention, the cell-binding molecules can be modified through attachment of a more specific peptide, a protein, or a drug, or the other functional molecules with a heterobifunctional cross linker such as with linkers of Amine-to-Nonselective (succinimidyl (NHS) -diazirine (SDA) , NHS ester / Azide) , Amine-to-Sulfhydryl (NHS ester / maleimide, NHS ester / pyridyldithiol, NHS esters / haloacetyl) , Sulfhydryl-to-Carbohydrate (Maleimide / Hydrazide, Pyridyldithiol / Hydrazide) , Hydroxyl-to-Sulfhydryl (Isocyanate / Maleimide) , Amine-to-DNA (NHS ester / Psoralen) , Amine-to-Carboxyl (Carbodiimide) .
[0286] In the SDA linkage modification, the NHS ester of SDA linker reacts with primary an amine group of a binding molecule backbone in pH 6~9 buffer to form a stable amide bond upon release of NHS. Then photoactivation of the diazirine with long-wave UV light (330-370nm) creates a reactive carbene intermediate that can react with an amine group of a more specific peptide or a protein or the other functional molecule. The order of these two steps can be different as this: an amine group of a functional molecule reacts with an SDA linker first, following by photoactive reaction of a binding molecule with long-wave UV light (330-370nm) . The SDA crosslinkers can be cleavable (with a disulfide bond inside such as SDAD linker) .
[0287]
[0288] In the NHS ester / Azide linkage modification, the NHS ester of the linker reacts with primary an amine group of a binding molecule backbone in pH 6~9 buffer to form a stable amide. Then an alkynyl group on a more specific peptide or a protein or the other functional molecule reacts to the azido on the other side of the linker via Azide-Alkyne Huisgen Cycloaddition to form a 1, 2, 3-triazole linkage (click chemistry) . Also, the NHS ester of the linker reacts with primary an amine group of a functional molecule in pH 6~9 buffer to form a stable amide. Then an alkynyl group being linked on a binding molecule reacts to the azido on the other side of the linker via 5 Azide-Alkyne Huisgen Cycloaddition to form a 1, 2, 3-triazole linkage.
[0289]
[0290] In the Amine-to-Sulfhydryl linkage modification, the NHS ester of the linker reacts with a primary amine group of a binding molecule backbone in pH 6~9 buffer to form a stable amide bond. Then a sulfhydryl on a more specific peptide or a protein or the other functional molecule reacts to the maleimide, or pyridyldithiol, or haloacetyl on the other side of the Amine-to sulfhydryl linker at pH 4.5 ~ 8.5 to form a thioether or a disulfide bond. The conjugation with the Amine-to-Sulfhydryl linker can be in different orders. For instance, an amine group of a functional molecule can be reacted with the linker to form an amide bond first, following by reaction with a sulfhydryl on a binding molecule. Also, a sulfhydryl group of a functional molecule can be reacted with the linker to form a thioether or a disulfide bond at pH 4.5 ~ 7 first, following by reaction with an amine group on a binding molecule at pH 6 ~ 9 to form an amide bond.
[0291]
[0292] In the Sulfhydryl-to-Carbohydrate linkage modification, the sulfhydryl group of a binding molecule can be reacted with the maleimide or the pyridyldithiol on the linker to form a thioether or a disulfide bond at pH 4.5 ~ 8 first, Then a carbonyl (aldehyde / ketone) group on a functional molecule reacts with the hydrazide to form an hydrazone bond. Also, the sulfhydryl group on a functional molecule can react with the linker to form a thioether or a disulfide bond at pH 4.5 ~ 8 first, following by reaction with a carbohydrate, or an oxidized carbohydrate, or a carbonyl (aldehyde / ketone) group on a binding molecule form an hydrazone bond.
[0293]
[0294] In the Hydroxyl-to-Sulfhydryl linkage modification, the sulfhydryl group of a binding molecule can be reacted with the maleimide or the pyridyldithiol on the linker to form a thioether or a disulfide bond at pH 6 ~ 8 first, Then a hydroxy group on a functional molecule reacts with the isocyanate on the linker to form a carbamate bond at pH 8 ~9. Also, the sulfhydryl group on a functional molecule can react with the linker to form a thioether or a disulfide bond at pH 6~ 8 first, following by reaction with a hydroxy on a binding molecule form a carbamate bond at pH 8~9.
[0295]
[0296] In yet another aspect of the invention, the production of antibodies used in the present invention involves in vivo or in vitro procedures or combinations thereof. Methods for producing polyclonal anti-receptor peptide antibodies are well-known in the art, such as in U.S. Pat. No. 4,493,795 (to Nestor et al) . A monoclonal antibody is typically made by fusing myeloma cells with the spleen cells from a mouse that has been immunized with the desired antigen ( G.; Milstein, C. (1975) . Nature 256: 495-497) . The detailed procedures are described in “Antibodies--A Laboratory Manual” , Harlow and Lane, eds., Cold Spring Harbor Laboratory Press, New York (1988) , which is incorporated herein by reference. Particularly monoclonal antibodies are produced by immunizing mice, rats, hamsters or any other mammal with the antigen of interest such as the intact target cell, antigens isolated from the target cell, whole virus, attenuated whole virus, and viral proteins. Splenocytes are typically fused with myeloma cells using polyethylene glycol (PEG) 6000. Fused hybrids are selected by their sensitivity to HAT (hypoxanthine-aminopterin-thymine) . Hybridomas producing a monoclonal antibody useful in practicing this invention are identified by their ability to immunoreact specified receptors or inhibit receptor activity on target cells.
[0297] A monoclonal antibody used in the present invention can be produced by initiating a monoclonal hybridoma culture comprising a nutrient medium containing a hybridoma that secretes antibody molecules of the appropriate antigen specificity. The culture is maintained under conditions and for a time period sufficient for the hybridoma to secrete the antibody molecules into the medium. The antibody-containing medium is then collected. The antibody molecules can then be further isolated by well-known techniques, such as using protein-A affinity chromatography; anion, cation, hydrophobic, or size exclusive chromatography (particularly by affinity for the specific antigen after Protein A, and sizing column chromatography) ; centrifugation, differential solubility, or by any other standard technique for the purification of proteins.
[0298] Media useful for the preparation of these compositions are both well-known in the art and commercially available and include synthetic culture media. An exemplary synthetic medium is Dulbecco's minimal essential medium (DMEM; Dulbecco et al., Virol. 8: 396 (1959) ) supplemented with 4.5 gm / l glucose, 20 mm glutamine, 20%fetal calf serum and with an anti-foaming agent, such as polyoxyethylene-polyoxypropylene block copolymer.
[0299] In addition, antibody-producing cell lines can also be created by techniques other than fusion, such as direct transformation of B lymphocytes with oncogenic DNA, or transfection with an oncovirus, such as Epstein-Barr virus (EBV, also called human herpesvirus 4 (HHV-4) ) or Kaposi's sarcoma-associated herpesvirus (KSHV) . See, U.S. Pat. Nos. 4,341,761; 4,399,121; 4,427,783; 4,444,887; 4,451,570; 4,466,917; 4,472,500; 4,491,632; 4,493,890. A monoclonal antibody may also be produced via an anti-receptor peptide or peptides containing the carboxyl terminal as described well-known in the art. See Niman et al., Proc. Natl. Acad. Sci. USA, 80: 4949-4953 (1983) ; Geysen et al., Proc. Natl. Acad. Sci. USA, 82: 178-182 (1985) ; Lei et al. Biochemistry 34 (20) : 6675-6688, (1995) . Typically, the anti-receptor peptide or a peptide analog is used either alone or conjugated to an immunogenic carrier, as the immunogen for producing anti-receptor peptide monoclonal antibodies.
[0300] There are also a number of other well-known techniques for making monoclonal antibodies as binding molecules in this invention. Particularly useful are methods of making fully human antibodies. One method is phage display technology which can be used to select a range of human antibodies binding specifically to the antigen using methods of affinity enrichment. Phage display has been thoroughly described in the literature and the construction and screening of phage display libraries are well known in the art, see, e.g., Dente et al, Gene. 148 (1) : 7-13 (1994) ; Little et al, Biotechnol Adv. 12 (3) : 539-55 (1994) ; Clackson et al., Nature 352: 264-628 (1991) ; Huse et al., Science 246: 1275-1281 (1989) .
[0301] Monoclonal antibodies derived by hybridoma technique from another species than human, such as mouse, can be humanized to avoid human anti-mouse antibodies when infused into humans. Among the more common methods of humanization of antibodies are complementarity-determining region grafting and resurfacing. These methods have been extensively described, see e.g. U.S. Pat. Nos. 5,859,205 and 6,797,492; Liu et al, Immunol Rev. 222: 9-27 (2008) ; Almagro et al, Front Biosci. 1; 13: 1619-33 (2008) ; Lazar et al, Mol Immunol. 44 (8) : 1986-98 (2007) ; Li et al, Proc. Natl. Acad. Sci. U S A. 103 (10) : 3557-62 (2006) each incorporated herein by reference. Fully human antibodies can also be prepared by immunizing transgenic mice, rabbits, monkeys, or other mammals, carrying large portions of the human immunoglobulin heavy and light chains, with an immunogen. Examples of such mice are: the Xenomouse. (Abgenix, Inc. ) , the HuMAb-Mouse (Medarex / BMS) , the VelociMouse (Regeneron) , see also U.S. Pat. No. 6,596,541, 6,207,418, No. 6,150,584, No. 6,111,166, No. 6,075,181, No. 5,922,545, Nos. 5,661,016, 5,545,806, 5,436,149 and 5,569,825. In human therapy, murine variable regions and human constant regions can also be fused to construct called “chimeric antibodies” that are considerably less immunogenic in man than murine mAbs (Kipriyanov et al, Mol Biotechnol. 26: 39-60 (2004) ; Houdebine, Curr Opin Biotechnol. 13: 625-9 (2002) each incorporated herein by reference) . In addition, site-directed mutagenesis in the variable region of an antibody can result in an antibody with higher affinity and specificity for its antigen (Brannigan et al, Nat Rev Mol Cell Biol. 3: 964- 70, (2002) ) ; Adams et al, J Immunol Methods. 231: 249-60 (1999) ) and exchanging constant regions of a mAb can improve its ability to mediate effector functions of binding and cytotoxicity.
[0302] Antibodies immunospecific for a malignant cell antigen can also be obtained commercially or produced by any method known to one of skill in the art such as, e.g., chemical synthesis or recombinant expression techniques. The nucleotide sequence encoding antibodies immunospecific for a malignant cell antigen can be obtained commercially, e.g., from the GenBank database or a database like it, the literature publications, or by routine cloning and sequencing.
[0303] Apart from an antibody, a peptide or protein that bind / block / target or in some other way interact with the epitopes or corresponding receptors on a targeted cell can be used as a binding molecule. These peptides or proteins could be any random peptide or proteins that have an affinity for the epitopes or corresponding receptors and they don't necessarily have to be of the immunoglobulin family. These peptides can be isolated by similar techniques as for phage display antibodies (Szardenings, J Recept Signal Transduct Res. 2003; 23 (4) : 307-49) . The use of peptides from such random peptide libraries can be similar to antibodies and antibody fragments. The binding molecules of peptides or proteins may be conjugated on or linked to a large molecules or materials, such as, but is not limited, an albumin, a polymer, a liposome, a nano particle, as long as such attachment permits the peptide or protein to retain its antigen binding specificity.

[0314] According to a further object, the present invention also concerns pharmaceutical compositions comprising the conjugate of the invention together with a pharmaceutically acceptable carrier for treatment of cancer and autoimmune disorders. The method for treatment of cancer and autoimmune disorders can be practiced in vitro, in vivo, or ex vivo. Examples of in vitro uses include treatments of cell cultures in order to kill all cells except for desired variants that do not express the target antigen; or to kill variants that express undesired antigen. Examples of ex vivo uses include treatments of hematopoietic stem cells (HSC) prior to the performance of the transplantation (HSCT) into the same patient in order to kill diseased or malignant cells. For instance, clinical ex vivo treatment to remove tumour cells or lymphoid cells from bone marrow prior to autologous transplantation in cancer treatment or in treatment of autoimmune disease, or to remove T cells and other lymphoid cells from allogeneic bone marrow or tissue prior to transplant in order to prevent graft-versus-host disease, can be carried out as follows. Bone marrow is harvested from the patient or other individual and then incubated in medium containing serum to which is added the conjugate of the invention, concentrations range from about 1 pM to 0.1 mM, for about 15 minutes to about 48 hours at about 37 ℃. The exact conditions of concentration and time of incubation (=dose) are readily determined by the skilled clinicians. After incubation the bone marrow cells are washed with medium containing serum and returned to the patient by i.v. infusion according to known methods. In circumstances where the patient receives other treatment such as a course of ablative chemotherapy or total-body irradiation between the time of harvest of the marrow and reinfusion of the treated cells, the treated marrow cells are stored frozen in liquid nitrogen using standard medical equipment.
[0315] A stable conjugate should also "retains its biological activity" in a pharmaceutical formulation, if the biological activity of the conjugate at a given time, e.g. 12 month, within about 20%, preferably about 10% (within the errors of the assay) of the biological activity exhibited at the time the pharmaceutical formulation was prepared as determined in an antigen binding assay, and / or in vitro, cytotoxic assay, for example.
[0316] For clinical in vivo use, the conjugate of the invention will be supplied as solutions or as a lyophilized solid that can be dissolved in sterile water for injection. Examples of suitable protocols of conjugate administration are as follows. Conjugates are given daily, weekly, biweekly, triweekly, once every four weeks or monthly for 8~54 weeks as an i.v. bolus. Bolus doses are given in 50 to 1000 ml of normal saline to which human serum albumin (e.g. 0.5 to 1 mL of a concentrated solution of human serum albumin, 100 mg / mL) can optionally be added. Dosages will be about 50 μg to 20 mg / kg of body weight per week, i.v. (range of 10 μg to 200 mg / kg per injection) . 4~54 weeks after treatment, the patient may receive a second course of treatment. Specific clinical protocols with regard to route of administration, excipients, diluents, dosages, times, etc., can be determined by the skilled clinicians.
[0317] Examples of medical conditions that can be treated according to the in vivo or ex vivo methods of killing selected cell populations include malignancy of any types of cancer, autoimmune diseases, graft rejections, and infections (viral, bacterial or parasite) .
[0318] The amount of a conjugate which is required to achieve the desired biological effect, will vary depending upon a number of factors, including the chemical characteristics, the potency, and the bioavailability of the conjugates, the type of disease, the species to which the patient belongs, the diseased state of the patient, the route of administration, all factors which dictate the required dose amounts, delivery and regimen to be administered.
[0319] In general terms, the conjugates via the linkers of this invention may be provided in an aqueous physiological buffer solution containing 0.1 to 10%w / v conjugates for parenteral administration. Typical dose ranges are from 1 μg / kg to 0.1 g / kg of body weight daily; weekly, biweekly, triweekly, or monthly, a preferred dose range is from 0.01 mg / kg to 20 mg / kg of body weight weekly, biweekly, triweekly, or monthly, an equivalent dose in a human. The preferred dosage of drug to be administered is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, the formulation of the compound, the route of administration (intravenous, intramuscular, or other) , the pharmacokinetic properties of the conjugates by the chosen delivery route, and the speed (bolus or continuous infusion) and schedule of administrations (number of repetitions in a given period of time) .
[0320] The conjugates of the present invention are also capable of being administered in unit dose forms, wherein the term “unit dose” means a single dose which is capable of being administered to a patient, and which can be readily handled and packaged, remaining as a physically and chemically stable unit dose comprising either the active conjugate itself, or as a pharmaceutically acceptable composition, as described hereinafter. As such, typical total daily / weekly / biweekly / monthly dose ranges are from 0.01 to 100 mg / kg of body weight. By way of general guidance, unit doses for humans range from 1 mg to 3000 mg per day, or per week, per two weeks (biweekly) , triweekly, or per month. Preferably the unit dose range is from 1 to 500 mg administered one to four times a month and even more preferably from 1 mg to 100 mg, once a week, or once biweekly, or once a triweekly. Conjugates provided herein can be formulated into pharmaceutical compositions by admixture with one or more pharmaceutically acceptable excipients. Such unit dose compositions may be prepared for use by oral administration, particularly in the form of tablets, simple capsules or soft gel capsules; or intranasally, particularly in the form of powders, nasal drops, or aerosols; or dermally, for example, topically in ointments, creams, lotions, gels or sprays, or via trans-dermal patches. The compositions may conveniently be administered in unit dosage form and may be prepared by any of the methods well known in the pharmaceutical art, for example, as described in Remington: The Science and Practice of Pharmacy, 21th ed.; Lippincott Williams &Wilkins: Philadelphia, PA, 2005.
[0321] Preferred formulations include pharmaceutical compositions in which a compound of the present invention is formulated for oral or parenteral administration.

Capsules can be in the form of a hard capsule or soft capsule, which are generally made from gelatin blends optionally blended with plasticizers, as well as a starch capsule. In addition, dosage unit forms can contain various other materials that modify the physical form of the dosage unit, for example, coatings of sugar, shellac, or enteric agents. Other oral dosage forms syrup or elixir may contain sweetening agents, preservatives, dyes, colorings, and flavorings. In addition, the active compounds may be incorporated into fast dissolve, modified-release or sustained-release preparations and formulations, and wherein such sustained-release formulations are preferably bi-modal. Preferred tablets contain lactose, cornstarch, magnesium silicate, croscarmellose sodium, povidone, magnesium stearate, or talc in any combination.

[0337] According to a still further object, the present invention is also concerned with the process of preparation of the conjugate of the invention. The conjugate and process of the present invention may be prepared in a number of ways well known to those skilled in the art. The Camptothecin analogs used in the conjugate can be synthesized, for example, by application or adaptation of the methods described below, or variations thereon as appreciated by the skilled artisan. The appropriate modifications and substitutions will be readily apparent and well known or readily obtainable from the scientific literature to those skilled in the art. In particular, such methods can be found in R.C. Larock, Comprehensive Organic Transformations, 2nd Edition, Wiley-VCH Publishers, 1999.
[0338] In the reactions described hereinafter, it may be necessary to protect reactive functional groups, for example hydroxy, amino, imino, thio or carboxy groups, where these are desired in the final product, to avoid their unwanted participation in the reactions. Conventional protecting groups may be used in accordance with standard practice, for examples see P.G. Wuts and T.W. Greene, Greene's Protective Groups in Organic Synthesis, Wiley-Interscience; 4th edition (2006) . Some reactions may be carried out in the presence of a base, or an acid or in a suitable solvent. There is no particular restriction on the nature of the base, acid and solvent to be used in this reaction, and any base, acid or solvent conventionally used in reactions of this type may equally be used here, provided that it has no adverse effect on other parts of the molecule. The reactions can take place over a wide range of temperatures. In general, we find it convenient to carry out the reaction at a temperature of from -80℃ to 150℃ (more preferably from about room temperature to 100℃) . The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, provided that the reaction is effective under the preferred conditions outlined above, a period of from 3 hours to 20 hours will usually suffice.
[0339] The work-up of the reaction can be carried out by conventional means. For example, the reaction products may be recovered by distilling off the solvent from the reaction mixture or, if necessary, after distilling off the solvent from the reaction mixture, pouring the residue into water followed by extraction with a water-immiscible organic solvent and distilling off the solvent from the extract. Additionally, the product can, if desired, be further purified by various well-known techniques, such as recrystallization, reprecipitation or the various chromatography techniques, notably column chromatography or preparative thin layer chromatography. The synthesis of the Camptothecin analogs and their conjugates of this invention are illustrated in the figures 1 ~32.
[0340] The conjugates of binding molecules with potent Camptothecin analogs are further illustrated but not restricted by the description in the following examples.
