Toward bifunctional antibody catalysis

Antibodies that catalyze the deprotonation of unactivated benzisoxazoles to give the corresponding salicylonitriles were prepared using as antigen a 2-aminobenzimidazolium derivative coupled to a carrier protein via its benzene ring. The hapten was designed to induce an antibody binding site with both a base and an acid, in position to initiate proton transfer and stabilize developing negative charge at the phenoxide leaving group, respectively. Consistent with this design, the catalysts exhibit bell-shaped pH-rate profiles, while chemical modification identified several functional groups that could participate in bifunctional catalysis. One of the antibodies, 13G5, is particularly notable in catalyzing the elimination of 6-glutaramidebenzisoxazole with a >105-fold rate acceleration over background and an effective molarity of >104 M for its catalytic base. These properties compare favorably to the efficiencies achieved by the best previously characterized antibodies with substantially more reactive substrates.

Synthesis and biological evaluation of D-amino acid oxidase inhibitors

D-Amino acid oxidase (DAAO) catalyzes the oxidation of D-amino acids including D-serine, a full agonist at the glycine site of the NMDA receptor. A series of benzo[d]isoxazol-3-ol derivatives were synthesized and evaluated as DAAO inhibitors. Among them, 5-chlorobenzo[d]isoxazol-3-ol (CBIO) potently inhibited DAAO with an IC50 in the submicromolar range. Oral administration of CBIO in conjunction with D-serine enhanced the plasma and brain levels of D-serine in rats compared to the oral administration of D-serine alone.

3-Amino-benzo[d]isoxazoles as novel multitargeted inhibitors of receptor tyrosine kinases

A series of benzoisoxazoles and benzoisothiazoles have been synthesized and evaluated as inhibitors of receptor tyrosine kinases (RTKs). Structure-activity relationship studies led to the identification of 3-amino benzo[d]isoxazoles, incorporating a N,N?-diphenyl urea moiety at the 4-position that potently inhibited both the vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor families of RTKs. Within this series, orally bioavailable compounds possessing promising pharmacokinetic profiles were identified, and a number of compounds demonstrated in vivo efficacy in models of VEGF-stimulated vascular permeability and tumor growth. In particular, compound 50 exhibited an ED50 of 2.0 mg/kg in the VEGF-stimulated uterine edema model and 81% inhibition in the human fibrosarcoma (HT1080) tumor growth model when given orally at a dose of 10 mg/kg/day.

Novel methylene bridged benzisoxazolyl imidazo[2,1-b][1,3,4]thiadiazoles (3a-f) were synthesized from benzisoxazolyl-3-acetic acid and thiosemicarbazide. Reaction of 3 with bromine in glacial acetic acid in the presence of anhydrous sodium acetate yielded the corresponding 5-bromo derivatives (4a-f). While compound 3 furnished the 5-nitroso derivatives (5a-f) on refluxing with sodium nitrite solution. Thiocyanato derivatives (6a-f) were obtained by treating the imidazothiadiazole 3 with bromine and potassium thiocyanate in glacial acetic acid at room temperature. The structures of the newly synthesized compounds were confirmed by IR, NMR, mass and elemental analysis. All the compounds were screened for their antibacterial and antifungal activities.
