Given the clinical importance of metallo-β-lactamases (MβLs), a new scaffold, N-substituted carbamylmethyl mercaptoacetate thioether, was constructed. The obtained molecules 1-16 inhibited MβLs from all three subclasses, but preferentially L1 from subclass B3. Compound 9 with a p-carboxyphenyl substituent exhibited the broadest spectrum with at least 70% inhibition of enzymes from all subclasses at 100 μM, while compound 5 with a p-methylphenyl substituent was the most potent inhibitor of any individual enzyme, with 97% inhibition at 100 μM and an IC50 value of 0.41 μM against L1. Isothermal titration calorimetry assays corroborate findings from UV-vis spectrophotometric assays that the inhibition of L1 by 5 is dose-dependent. Docking studies suggest that the carboxyl group, the sulfide atom, and the carbonyl group of the carbamyl coordinate Zn2 in a chelating fashion. Using E. coli cells expressing L1, 6 and 8 were able to decrease cefazolin minimum inhibitory concentration 8-fold.

A NOVEL series of 1,4-benzoxazinone derivatives were synthesized and characterized using FT-IR , 1H-NMR, 13C-NMR and Mass spectroscopy. These compounds were in vitro screened against several bacterial species gram positive and gram negative as well as Candida albicans and found exhibiting moderate to potent activity. The antioxidant study was confirmed for the synthesized derivatives against 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical. Docking study for the potent compound 8 against glucosamine-6-phosphate synthase , the target enzyme for the antimicrobial agents was explored to explain the interactions of the discovered hits with in the amino acid residues of the enzyme active side. The docking parameters enhanced the activity of new compound as promising antimicrobial agents.
Discovery and characterization of novel imidazopyridine derivative CHEQ-2 as a potent CDC25 inhibitor and promising anticancer drug candidate

Cell division cycle (CDC) 25 proteins are key phosphatases regulating cell cycle transition and proliferation via the interactions with CDK/Cyclin complexes. Overexpression of CDC25 proteins is frequently observed in cancer and is related to aggressiveness, high-grade tumors and poor prognosis. Thus, inhibiting CDC25 activity in cancer treatment appears a good therapeutic strategy. In this article, refinement of the initial hit XDW-1 by synthesis and screening of a focused compound library led to the identification of a novel set of imidazopyridine derivatives as potent CDC25 inhibitors. Among them, the most potent molecule was CHEQ-2, which could efficiently inhibit the activities of CDC25A/B enzymes as well as the proliferation of various different types of cancer cell lines in vitro assay. Moreover, CHEQ-2 triggered S-phase cell cycle arrest in MCF-7, HepG2 and HT-29 cell lines, accompanied by generation of ROS, mitochondrial dysfunction and apoptosis. Besides, oral administration of CHEQ-2 (10 mg/kg) significantly inhibited xenografted human liver tumor growth in nude mice, while demonstrated extremely low toxicity (LD50 > 2000 mg/kg). These findings make CHEQ-2 a good starting point for further investigation and structure modification.

A simple and efficient method has been developed for the synthesis of substituted morpholines by a sequence of coupling, cyclization, and reduction reactions of easily available amino alcohols and α-halo acid chlorides. Various mono-, di-, and trisubstituted morpholines, spiro morpholines, and ring-fused morpholines, as well as morpholine homologues, were synthesized in good to excellent yields by a single methodology under similar reaction conditions. The method was also used in a multigram synthesis of (3S)-3-methylmorpholine.
