[0005] STATEMENT AS TO FEDERALLY SPONSORED RESEARCH
[0006] This invention was made with government support under 1 R21 NS120884- 01 Al and 1 R21 NS120839-01 Al awarded by the National Institutes of Health (NIH). The government has certain rights in the invention.
[0007] TECHNICAL FIELD
[0008] This invention generally relates to antidote chemistry for treatment of organophosphate intoxication. In alternative embodiments, provided are polyheterocyclic uncharged bisoxime antidotes.
[0009] BACKGROUND
[0010] Catalytic activity of hAChE is essential in diaphragm of the peripheral nervous system and in the brain (the central nervous system; CNS). Currently approved antidotes (pralidoxime, obidoxime, asoxime) are all charged pyridinium derivatives that can not reach CNS in order to reactivate brain hAChE. They are effective only in the peripheral nervous system.
[0011] Polyheterocyclic uncharged bisoximes are uncharged molecules that have potential to spontaneously diffuse into CNS and reactivate OP inhibited brain hAChE, in addition to be effective reactivators of the peripheral system hAChE in the diaphragm. Maintaining normal diaphragm function and preventing brain seizures are both related to reactivation of organophosphate (OP) inhibited hAChE and are essential for saving life in OP intoxication. PATENT
[0012] 0321.153519PCT / SD2024-022
[0013] Standard, currently approved pyridinium-based cationic antidotes (pralidoxime, obidoxime, asoxime) are not capable of crossing BBB and reactivating brain AChE. They cannot provide full and fast recovery from the OP intoxication.

[0047] DETAILED DESCRIPTION
[0048] In alternative embodiments, provided are polyheterocyclic uncharged bisoxime antidotes. In alternative embodiments, provided is a new class of polyheterocyclic uncharged bisoximes that we designed and synthesized, which can quickly recover activity of organophosphate (OP) inhibited (nerve agent or pesticide OP) human acetylcholinesterase (AChE), in minutes upon poisoning, much more efficiently than existing antidotes in the current use. hAChE is the target enzyme in OP intoxication and its inhibition can be lethal.
[0049] Polyheterocyclic bisoximes are several-fold more effective reactivators of OP inhibited hAChE in vitro than any previously disclosed centrally active antidotes, such as RS194B (described in the PCT / US2014 / 016639) or LG703 (described in the PCT / US2020 / 034051). Consequentially, the recovery is faster and occurs at a lower reactivator dose.
[0050] The novel polyheterocyclic bisoximes as provided herein are uniquely better than approved antidotes under 1) because they have potential for faster and more complete reactivation of OP inhibited hAChE in both peripheral and central nervous system, while standard antidotes cannot access central nervous system.
[0051] Our novel polyheterocyclic bisoximes are uniquely better than monoheterocyclic monoximes and bisoximes listed under 2) and 3) because in vitro they have been demonstrated to act several-fold faster resulting in potential to provide life-saving recovery of hAChE activity in both peripheral and central nervous systems, at a fraction of time and at lower dose, than what monoheterocyclic momoximes and bisoximes can do.
[0052] Because of their inability to cross biological membranes currently approved antidotes have to be administered intramuscularly or intravenously only to organophosphate (OP) intoxicated patients. In contrast, polyheterocyclic bisoximes as provided herein are uncharged and have capacity to diffuse spontaneously across biological membranes and have potential for oral administration. PATENT 0321.153519PCT / SD2024-022
[0053] In alternative embodiments, polyheterocyclic uncharged bisoxime antidotes as provided herein are formulated as tablets, pills, geltabs, capsules, powders and the like. Storage and distribution of antidotes in a solid state (as tablets, pills, geltabs, capsules, powders and the like) simplifies tremendously ability to protect large population of OP- exposed individuals from poisoning due to improved compound stability in a solid state, facile distribution of a pill and simple and quick administration of exposed patients.
[0054] In alternative embodiments, polyheterocyclic bisoxime antidotes as provided herein are uncharged and will cross biological membranes including blood-brain- barrier (BBB) unlike standard pyridinium-based antidotes.
[0055] In alternative embodiments, polyheterocyclic bisoxime antidotes as provided herein are formulated to be given to OP -intoxicated patients either by inhalation, sublingually, intramuscularly, intravenously or as an oral pill.
[0056] Polyheterocyclic bisoximes are uncharged and will cross biological membranes including blood-brain-barrier (BBB) unlike standard pyridinium-based antidotes. They are uncharged but have either three or four ionizable groups. In solution, such as human blood, ionization equilibrium will be established where compound will be either uncharged, have one or two protonated centers or have both one or two protonated centers with two anionic centers. Three forms should be dominant: uncharged, singly protonated and zwitterionic singly protonated with one anionic center. The uncharged form will first cross the BBB, then it will re-equilibrate to form protonated form that will bind to the inhibited molecular target (OP-hAChE). This binding was demonstrated to be better than the monoheterocyclic monoxime or bisoxime binding. In the next step reactive oxime group of the polyheterocyclic bisoxime will attack P atom of OP-hAChE conjugate in significantly more efficient and rapid manner than what was observed for monoheterocyclic monoximes or bisoximes. As a result recovery of catalytic activity of OP inhibited hAChE will be faster and more complete, at a lower antidote dose, compared to all prior art antidotes.
[0057] Because of their inability to cross biological membranes currently approved antidotes have to be administered intramuscularly or intravenously only to organophosphate (OP) intoxicated patients. In contrast, polyheterocyclic bisoximes as provided herein are uncharged and have capacity to diffuse spontaneously across biological membranes and have potential for oral administration. PATENT

[0129] Dosaging
[0130] The pharmaceutical compositions and formulations as provided herein can be administered for prophylactic and / or therapeutic treatments. In therapeutic applications, compositions are administered to a subject already exposed to a toxin, or exposed to any agent or chemical causing or resulting in excessive acetylcholine stimulation in the brain, for example, exposure to a drug, a drug overdose, or a poisoning or a toxic exposure to a drug, and optionally the drug overdose causing the excessive acetylcholine stimulation is caused at least in part by: physostigmine, neostigmine, pyridostigmine, diisopropylfluorophosphate, or echothiophate an amount sufficient to cure, alleviate or partially arrest the clinical manifestations of the agent and / or its complications (a “therapeutically effective amount”).
[0131] The amount of pharmaceutical composition adequate to accomplish this is defined as a "therapeutically effective dose." The dosage schedule and amounts effective for this use, i.e., the “dosing regimen,” will depend upon a variety of factors, including the stage of the disease or condition, the severity of the disease or condition, the general state of the patient's health, the patient’s physical status, age and the like. In calculating the dosage regimen for a patient, the mode of administration also is taken into consideration.
[0132] The dosage regimen also takes into consideration pharmacokinetics parameters well known in the art, i.e., the active agents’ rate of absorption, bioavailability, metabolism, clearance, and the like (see, for example, Hidalgo- Aragones (1996) J. Steroid Biochem. Mol. Biol. 58:611-617; Groning (1996) Pharmazie 51 :337-341; Fotherby (1996) Contraception 54:59-69; Johnson (1995) J. Pharm.

[0147] Synthetic Schemes for Making Exemplary Compounds
[0148] General procedure A (Alkylation reaction) To a solution of amine or amine hydrochloride (1 equiv (equivalents)) in ACN (0.2 M) was added successively bromoacetonitrile (1.1 equiv or 2.2 equiv) and potassium carbonate (2.5 equiv or 4.5 equiv) and the mixture was heated to 60 °C for 4 hrs. The reaction mixture was then concentrated under reduced pressure and the solid residue redissolved in water and EtOAc. The aqueous layer was extracted twice with EtOAc and the combined organic fractions were washed with brine 2X, dried and concentrated under reduced pressure. Purification over flash chromatography (Hexanes / EtOAc or DCM / MeOH) provided the desired compounds as clear oils.
[0149] General procedure B (LiAHB reduction) To a solution of Lithium aluminium hydride (4 equiv) in dry THF (0.1 M) was added a solution of the dicyano derivative (1 equiv) in dry THF (0.1 M) at r.t. and the mixture was heated to 90 °C for 4 hrs. The reaction was quenched at r.t. with water (2 equiv) and a 10% NaOH solution (6 equiv). The white solid was filtered off, rinced with THF and the filtrate was concentrated under reduced pressure. The crude was purified over silica (DCM / MeOH : 90 / 10-75 / 25 to DCM / Me0H / NH40H 70 / 20 / 10) to furnish the bis-primary amines as yellow oils.
[0150] General procedure C (Acylation reaction) To a solution of the desired bis-primary amine (1 equiv) in absolute EtOH (0.1 M) was added a solution of ethyl (E)-2- (hydroxyimino)acetate (2.5 equiv) and the mixture was heated to 90 °C for 72 hrs. It was then concentrated under reduced pressure. Purification over silica (DCM / MeOH : 90 / 10 to 70 / 30) furnished the desired bis oxime as a white solid after trituration in cold MeOH.
[0151] General procedure D (Horner-Emmons-Wadsworth reaction) To a solution of diethyl cyanomethylphosphonate (1.3 equiv) in dry THF (0.1 M) was added sodium hydride (60% in oil, 1.2 equiv) portionwise. The mixture was stirred at r.t. for 15 min before the desired ketone (1 equiv) was added and the reaction stirred at r.t. for 3 hrs. The reaction was then quenched with water. The aqueous layer was extracted with EtOAc PATENT 0321.153519PCT / SD2024-022 twice and the combined organic fractions were washed with brine, dried and concentrated under reduced pressure. Purification over silica (Hexanes / EtOAc : 98 / 2 to 85 / 15) provided the desired unsaturated cyano derivative as a colorless oil.
[0152] General procedure E (Hydrogenation andBoc deprotection) To a solution of the desired unsaturated cyano derivative (1 equiv) in MeOH (0.1 M) under N2 was added palladium on carbon (10% Wt, 0.1 equiv) and the solution was backfilled three times with hydrogen. The mixture was stirred at r.t. for 6 hrs before it was put back under N2, then filtered over Celite and rinced with MeOH. The filtrate was then concentrated to furnish the desired saturated cyano derivatives a pale-yellow oil which were dissolved in MeOH (0.1 M) before addition of a 4M HC1 solution in 1,4- dioxane (15 equiv). The mixture was stirred at r.t. for 3 hrs before it was concentrated under reduced pressure and precipitated out of DCM / Hexanes to furnish the desired amine hydrochloride as a light brown solid was used in the next step without further purification.

[0177] Example 2: In vitro reactivation efficacy of two exemplary polyheterocyclic bisoximes
[0178] Exemplary polyheterocyclic uncharged bisoxime antidotes were tested as reactivators of paraoxon inhibited human acetylcholinesterase (hAChE) in vitro, with positive results. The in vitro reactivation efficacy of two most efficient tested polyheterocyclic antidote (out of four synthesized) was shown to approach in vitro efficacy of MMB4, one of most effective aldoxime antidotes of all aldoximes. MMB4 is ineffective in the CNS due to its cationic charge, our polyheterocyclic aldoximes are not charged and are expected to cross BBB and function effectively in the CNS.
[0179] In vitro experimental data efficacy with functional data for reactivation rates analyzed with deconstructed kinetic constants for four polyheterocyclic bisoxime compounds in reactivation of four OP inhibited hAChE forms: paraoxon-hAChE, VX-hAChE, sarin-hAChE and cyclosarin-hAChE.
[0180] In vitro reactivation of POX-hAChE by exemplary polyheterocyclic uncharged bisoxime antidotes as provided herein is illustrated in FIG. 5, and their reactivation rate constants compared to the monoheterocyclic bis-oxime LG-703, monoheterocyclic monoxime RS194B and cationic pyridinium -based aldoximes 2PAM and MMB4 are given in the Table 1, as illustrated in FIG. 6.
[0181] Table 1 (FIG. 6) shows kinetic constants for reactivation of OP-hAChE conjugates, in vitro, by polyheterocyclic bis-oximes compared to the monoheterocyclic bis-oxime LG-703, monoheterocyclic monoxime RS194B and cationic pyridinium-based aldoximes 2PAM and MMB4. Listed are: maximal reactivation rate constant k2 (min-1), Michaelis-Menten type constant Kox(mM), and the overall second order reactivation rate constant kr(Mimin'1).
[0182] Example 3 : Maximal tolerated doses of polyheterocyclic bis-oximes in mice
[0183] Tolerability of the two exemplary polyheterocyclic bis-oximes, TAL-1025 and TAL-1093, was determined in female CD-I mice, upon i.v., i.m. and p.o. bis-oxime administration to mice. The bis-oximes were aseptically dissolved in the 100 mM citrate buffer pH 5 and sterile filtered prior to administration to mice.
[0184] A single i.m. administration of exemplary TAL 1025 or TAL 1093 (20, 40, 80 and 160 mg / kg) to 2 female CD-I mice per group was well tolerated with no mortality / morbidity or clinical signs indicative of significant toxicity. While a maximum tolerated dose (MTD) could not be established after a single intramuscular PATENT 0321.153519PCT / SD2024-022
[0185] (i.m.) dose of each test article, the MTD for exemplary TAL 1025 was greater than (>) 20 mg / kg after intravenous (i.v.) administration and > 160 mg / kg after a single i.m. dose. The MTD for exemplary TAL 1093 was between 80 mg / kg and 160 mg / kg (i.m.) and between 10 mg / kg and 20 mg / kg (i.v.).
[0186] Thus, both of the exemplary bis-oximes were tolerated in CD-I mice several- fold better than the standard of care antidote 2PAM (LD50 for mice intramuscular (i.m.) 106 mg / kg) and comparable to the monoheterocyclic monoxime RS194B (LD50 for mice i.m. 500 mg / kg).
[0187] Example 4: In vivo therapeutic efficacy of exemplary polyheterocyclic bis-oxime in OP-exposed mice
[0188] The antidotal effect of the exemplary polyheterocyclic bisoxime TAL- 1025 was tested, by intramuscular (i.m.) administration of the bis-oxime and atropine (10 mg / kg) 1 min after an OP compound (given subcutaneously (s.c.)) to male CD-I mice. The OP dose was escalated by geometric progression from 1 x LD50 up to the dose at which the mortality matches the data shown in Thomson and Weil tables for calculating LD50. The bis-oxime antidote dose was selected to be 20 mg / kg, well below their respective MTD and what was significantly lower compared to the common monoheterocyclic monoxime RS194B dose (125 mg / kg) and slightly lower than the approved 2PAM antidote dose (26.4 mg / kg, as previously described: Radic et al., JBC 2012). The antidotal efficacy against OP poisoning given in the Table 2 (FIG. 7) is expressed as protective index (PI= LD50+oxime / LD50). Symptoms of poisoning were carefully monitored up to 24 h after exposure to OP, and compared between given antidotal post-treatments. Survival within 24 h after OP exposure also allowed us to determine the highest dose of OP compound at which all animals survived 24 h with oxime therapy (MDP).
[0189] Table 2 (FIG. 7) shows data from the therapy of OP exposed mice with the exemplary polyheterocyclic uncharged TAL- 1025 bis-oxime as provided herein. The results are presented as protective index, PI (95% confident limits are given in parentheses) and maximal dose of OP that all mice survived, MDP. Mice were treated i.m. with 1 / 4 of oxime’s LD50 + 10 mg / kg atropine, 1 minute after OP application given s.c.. Literature values for monoheterocyclic monoxime RS194B and pyridinium-based cationic monoxime 2PAM are given for comparison. PATENT 0321.153519PCT / SD2024-022
[0190] In vivo determined therapeutic efficacy of a representative polyheterocyclic bis-oxime antidote described as a PI, proved comparable or better than that of the approved antidote 2PAM (Table 2), considering a lower dose and unique property of TAL-1025 to act antidotaly in the CNS, unlike 2PAM. The efficacy of polyheterocyclic TAL-1025 in the paraoxon-exposed mice proved several -fold better than the one of the previously published centrally active antidote RS194B (Table 2), and at a much lower dose.
[0191] Example 5: Pharmacokinetic analysis and bioavailability of polyheterocyclic bisoximes in CD-I mice
[0192] The plasma pharmacokinetics of TAL-1025 and TAL-1093 in female CD-I mice was determined following a single i.m., intravenous (i.v.), or oral (p.o.) dose administration. The bis-oximes were aseptically dissolved in the 100 mM citrate buffer pH 5 and sterile filtered prior to administration to mice.
[0193] The plasma concentration data was analyzed using PHOENIX® WINNONLIN® (version 8.5) software to perform noncompartmental pharmacokinetic analysis with the sparse sampling feature. The doses administered were input into the program as mg / kg, and as a result, no additional corrections for individual body weights of the animals were necessary. The following plasma PK parameters were determined: maximum plasma concentration (Cmax), time to reach maximum plasma concentration (Tmax), area under the plasma concentration-time curve to the last timepoint (AUClast) and extrapolated to infinity (AUCinf), terminal phase elimination half-life (t 1 / 2), and mean residence time to the last time point (MRTlast) and extrapolated to infinity (MRTinf). For the iv groups only, theoretical concentration at time 0 (CO), volume of distribution at steady state (Vss), and clearance (Cl) were calculated. For the im and po groups only, bioavailability (F) was calculated by comparing AUCinf values corrected for the administered dose.
[0194] The results of the pharmacokinetic analysis following a single 20 mg / mg i.v., 160 mg / kg i.m., or 160 mg / kg p.o. dose administration of the exemplary TAL-1025 or TAL-1093 to female CD-I mice are as follows. When the exemplary TAL-1025 was administered to mice, the CO was 11,400 ng / ml for the i.v. group, while the Cmax for the i.m. group (74,400 ± 6,930 ng / ml) was observed at the first blood collection timepoint of 0.083 hr, and the Cmax for the p.o. group (8,840 ± 2,610 ng / ml) was observed at a Tmax of 1 hr. Plasma exposure values based on AUC.inf were 4,040, PATENT 0321.153519PCT / SD2024-022
[0195] 34,200, and 15,700 hrng / ml for the i.v., i.m., and p.o. groups, respectively. The the exemplary MRTinf was 0.886, 0.754, and 2.58 hr, and tl / 2 was 1.20, 1.18, and 3.05 hr for the i.v., i.m., and p.o. groups, respectively. Cl and Vss for the i.v. group were 4,950 ml / hr / kg and 4.39 1 / kg, respectively. Bioavailability of TAL 1025 was 106% for the i.m. group and 49% for the p.o. group. When the exemplary TAL 1093 was administered to mice, the Co was 17,600 ng / ml for the i.v. group, while the Cmax for the i.m. group (84,100 ± 21,900 ng / ml) was observed at the first blood collection time point of 0.083 hr, and the Cmax for the p.o. group (685 ± 135 ng / ml) was observed at a Tmax of 1 hr. Plasma exposure based on AUCinf was 2,890, 26,200, and 1,460 hr.ng / ml for the i.v., i.m., and p.o. groups, respectively. The MRTinf was 0.729, 0.528, and 2.19 hr, and tl / 2 was 2.62, 1.04, and 3.47 hr for the i.v., i.m., and p.o. groups, respectively. Cl and Vss for the i.v. group were 6,930 ml / hr / kg and 5.05 1 / kg, respectively. Bioavailability of TAL 1093 was 113% for the i.m. group and 6.3% for the p.o. group.
[0196] In conclusion the plasma exposure based on the AUCinf was higher for TAL - 1025 by all routes of administration. Both exemplary bis-oximes exhibited very good plasma exposure. Bioavailability for both test articles was outstanding at approximately 100% after im administration. The oral bioavailability was also outstanding for TAL-1025 at 49%, and much greater than for TAL -1093 (at 6.3%).
[0197] Both exemplary polyheterocyclic bis-oximes exhibited much higher bioavailability than the standard of care, cationic pyridinium-based antidote 2PAM, and comparable or better bioavailability compared to the uncharged monoheterocyclic monoxime RS194B (as previously described: Radic et al., JBC 2012).
