Synthesis and in-vitro evaluation of 2-amino-4-arylthiazole as inhibitor of 3D polymerase against foot-and-mouth disease (FMD)
摘要:
Foot-and-mouth disease (FMD) is a highly contagious vesicular disease of livestock caused by a highly variable RNA virus, foot-and-mouth disease virus (FMDV). One of the targets to suppress expansion of and to control FMD is 3D polymerase (FMDV 3Dpol). In this study, 2-amino-4-arylthiazole derivatives were synthesized and evaluated for their inhibitory activity against FMDV 3Dpol. Among them, compound 20i exhibited the most potent functional inhibition (IC50 = 039 mu M) of FMDV 3D polymerase and compound 24a (EC50 = 13.09 mu M) showed more potent antiviral activity than ribavirin (EC50 = 1367 mu M) and T1105 (EC50 = 347 mu M) with IBRS-2 cells infected by the FMDV O/SKR/2010 strain.

methodology for the synthesis of fused bicyclic 2-aminothiazolyl compounds has been developed, using cyclocondensation of aromatic thioureas with α,β-epoxy cycloketones in alcohol under microwave irradiation without any catalyst. The product distribution is related to the ring size of α,β-epoxy cycloketones. Mechanistic studies suggest that the reactions share analogous bicyclic dihydroxy intermediates but
A series of fused bicyclic 2-aminothiazolyl compounds were synthesized and evaluated for their synergistic effects with polymyxin B (PB) against Klebsiella pneumoniae (SIPI-KPN-1712).
