novel class of inhibitors that are potent and specific for caspases-2, -3, -6, -7, -8, -9, and -10. The second-order rate constants are in the order of 10(6) M(-1) s(-1). The aza-peptide Michael acceptor inhibitor 18t (Cbz-Asp-Glu-Val-AAsp-trans-CH=CH-CON(CH(2)-1-Naphth)(2) is the most potent compound and it inhibits caspase-3 with a k(2) value of 5620000 M(-1) s(-1). The inhibitor 18t is 13700, 190

A series of parallel reactions were carried out for the tandem Ugi/Diels–Alder reaction on our MPEG–O–CH2- platform. Ninety-six out of a 100 entries were successful to give complex heterotricycles. The stereoselectivity was found not to be influenced by the building blocks used for amine and carboxylic acid components. An unexpected side pathway was found but was suppressed by employing appropriate
The present disclosure provides compositions for inhibiting proteases, methods for synthesizing the compositions, and methods of using the disclosed protease inhibitors. Aspects of the disclosure include a peptidyl propenoyl hydrazide compositions that inhibit proteases, for example cysteine proteases, either in vivo or in vitro.
