Abstract

Compounds 10 (ND-322) and 15 (ND-364) are potent selective inhibitors for gelatinases, matrix metalloproteinase 2 (MMP2) and matrix metalloproteinase 9 (MMP9). However, both of them are racemates. Herein we report facile synthesis of optically active (R)- and (S)-enantiomers of compounds 10 and 15. And the sulfonyl of 15 was transformed to sulfinyl to obtain four epimeric mixtures. All synthesized thiirane-based compounds were evaluated in MMP2 and MMP9 inhibitory assays. Our results indicated that the configuration of thiirane moiety had little effects on gelatinase inhibition, but the substitution of sulfinyl for sulfonyl was detrimental to gelatinase inhibition. Besides, all target compounds exhibited no inhibition against Other two Zn(2+) dependant metalloproteases, Aminopeptidase N (APN) and histone deacetylases (HDACs), which confirmed the unique Zn(2+) chelation mechanism of thiirane moiety against gelatinases.
