The invention describes a vitamin receptor binding drug delivery conjugate, and preparations therefor. The drug delivery conjugate consists of a vitamin receptor binding moiety, a bivalent linker (L), and a drug. The vitamin receptor binding moiety includes vitamins, and vitamin receptor binding analogs and derivatives thereof, and the drug includes analogs and derivatives thereof. The vitamin receptor binding moiety is covalently linked to the bivalent linker, and the drug, or the analog or the derivative thereof, is covalently linked to the bivalent linker, wherein the bivalent linker (L) includes components such as spacer linkers, releasable linkers, and heteroatom linkers, and combinations thereof. Methods and pharmaceutical compositions for eliminating pathogenic cell populations using the drug delivery conjugate are also described.

Novel analogues and derivatives of novobiocin are provided, including compounds having modifications to the amide side chain, coumarin ring, and sugar moieties. The compounds of the present invention are useful as heat shock protein 90 inhibitors, and may be used as anticancer and neuroprotective agents.

Novel site-specific mono-conjugates of Granulocyte Colony Stimulating Factor (G-CSF) are hereby described, with analogues and derivatives thereof, which stimulate proliferation and differentiation of progenitor cells to mature neutrophiles. These conjugates have been obtained using transglutaminase to covalently and site-specifically bind a hydrophilic, non-immunogenic polymer to a single glutamine residue of the human G-CSF native sequence and analogues thereof. These novel site-specific mono-conjugated derivatives are recommended for therapeutic use since they are stable in solution and exhibit significant biological activity in vitro and a longer bloodstream half-life, as compared to the non-conjugated protein, with a consequent prolonged pharmacological activity.

The present invention relates to triazine compounds and their analogs and derivatives, and methods and compositions comprising these compounds. The compounds and compositions of this invention are useful for, among other things, treating pathophysiological conditions arising from inflammatory responses, inhibiting or blocking glycated protein produced induction of the signaling-associated inflammatory response in endothelial cells, inhibiting smooth muscle proliferation, treating vascular occlusive conditions characterized by smooth muscle proliferation such as restenosis and atherosclerosis, and the like.

This invention is in the area of cobalamin-mediated delivery of nucleic acids and analogs and derivatives thereof to a host to affect gene expression.

The present invention relates to antibody-drug conjugate compounds of Formula I: Ab (L D)p I where one or more macrocyclic depsipeptide drug moieties (D), selected from Aplidin, Didemnin B, Kahalalide F, and analogs and derivatives therefrom, are covalently attached by a linker (L) to an antibody (Ab) which binds to one or more tumor-associated antigens or cell-surface receptors. These compounds may be useful in methods of diagnosis or treatment of cancer, and other diseases and disorders.

Human proIslet Peptides (HIP) and HIP analogs and derivatives thereof, derived from or homologous in sequence to the human REG3A protein, chromosome 2p12, are able to induce islet neogenesis from endogenous pancreatic progenitor cells. Human proIslet Peptides are used either alone or in combination with other pharmaceuticals in the treatment of type 1 and type 2 diabetes and other pathologies related to aberrant glucose, carbohydrate, and/or lipid metabolism, insulin resistance, overweight, obesity, polycystic ovarian syndrome, eating disorders and the metabolic syndrome.

Compounds and compositions of azacytosine analogs and derivatives are provided. In one aspect of the invention, analogs or derivatives of decitabine and azacitidine are provided with modification at the 2-, 4-, or 6-position of the triazine ring, at the 1′-6′position of the ribose ring, or combinations thereof. Methods of using, synthesizing and manufacturing these analogs and derivatives are also provided. These compounds can be formulated into pharmaceutical compositions that can be used for treating any disease associated with aberrant DNA methylation, or a disease or condition that is sensitive to the treatment with decitabine or azacitidine, such as hematological disorders, tumors and cancers.

The present invention provides a method of determining or identifying or isolating a cell-penetrating peptide (CPP) or analog or derivative thereof having cell-type selectivity and/or at least capable of passing through a Blood Brain Barrier of an animal subject. This invention also provides CPPs and analogs and derivatives thereof, such as those set forth in SEQ ID NOs: 1-27 of the Sequence Listing, and compositions comprising one or more of the CPPs, including conjugates in which a CPP or analog or derivative thereof is linked to a cargo molecule. The invention also provides methods for transporting cargo molecules across cell membranes to specific locations within cells, and for treating, preventing and/or diagnosing diseases that are treatable by a cargo molecule to which a CPP or analog or derivative of the invention is attached. The invention also provides tailored peptide libraries for use in identifying or isolating CPPs.

The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of glioblastoma multiforme. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N⁷ methylation. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is active against tumors that are refractory to temozolomide; the drug acts independently of the MGMT repair mechanism.

The invention relates to truncated GLP-1 analogues, in particular a GLP-1 analogue which is a modified GLP-1(7-35) (SEQ ID No 1) having: i) a total of 2, 3, 4, 5 6, 7, 8, or 9 amino acid substitutions as compared to GLP-1(7-35), including a) a Glu residue at a position equivalent to position 22 of GLP-1(7-35), and b) an Arg residue at a position equivalent to position 26 of GLP-1(7-35); as well as derivatives thereof, and therapeutic uses and compositions. These analogues and derivatives are highly potent, have a good binding affinity to the GLP-1 receptor, also to the extracellular domain of the GLP-1 receptor, which is of potential relevance achieving long-acting, stable GLP-1 compounds with a potential for once weekly administration.
