Thiazolidin-4-one derivative 3 was synthesized by the transformation of chloroacetamide derivative 2 with NH4SCN.The condensation of 3 with p-anisaldehyde afforded the corresponding arylidene derivative 4. Also, the alkylation of chloroacetamide derivative 2 with different heterocyclic compounds was investigated. Annulation of 5-amino-3-methylisoxazole (1) with α-halocarbonyl compounds 12 and 14 furnished pyrrolo[3,2-d]isoxazole and isoxazolo[5,4-b]azepin-6-one derivatives 13 and 15, respectively, while reaction of 1 with 1-chloro-4-(chloromethyl)benzene gave the monoalkylated product 17. The newly synthesized compounds were screened for their antitumor activity, and the geometry optimizations are in a good agreement with the experimentally observed data.

Protein-tyrosine phosphatase 1B (PTP1B) is a negative regulator of insulin signaling pathway and has been validated as a therapeutic target for type 2 diabetes. A wide variety of scaffolds have been included in the structure of PTP1B inhibitors, one of them is the benzimidazole nucleus. Here, we report the design and synthesis of a new series of di- and tri- substituted benzimidazole derivatives including their kinetic and structural characterization as PTP1B inhibitors and hypoglycemic activity. Results show that compounds 43, 44, 45, and 46 are complete mixed type inhibitors with a Ki of 12.6 μM for the most potent (46). SAR type analysis indicates that a chloro substituent at position 6(5), a β-naphthyloxy at position 5(6), and a p-benzoic acid attached to the linker 2-thioacetamido at position 2 of the benzimidazole nucleus, was the best combination for PTP1B inhibition and hypoglycemic activity. In addition, molecular dynamics studies suggest that these compounds could be potential selective inhibitors from other PTPs such as its closest homologous TCPTP, SHP-1, SHP-2 and CDC25B. Therefore, the compounds reported here are good hits that provide structural, kinetic, and biological information that can be used to develop novel and selective PTP1B inhibitors based on benzimidazole scaffold.
