The present invention relates to the discovery of new class of hydrolysable amino acid derivatives and absorbable polyester amides, polyamides, polyepoxides, polyureas and polyurethanes prepared therefrom. The resultant absorbable polymers are useful for drug delivery, tissue engineering, tissue adhesives, adhesion prevention, bone wax formulations, medical device coatings, stents, stent coatings, highly porous foams, reticulated foams, wound care, cardiovascular applications, orthopedic devices, surface modifying agents and other implantable medical devices. In addition, these absorbable polymers should have a controlled degradation profile.

The present invention relates to a compound exhibiting inhibitory activity of at least one of malate dehydrogenases I (MDH1) and malate dehydrogenases 2 (MDH2), and a pharmaceutical composition for preventing or treating cancer comprising the same as an active ingredient. The inventors of the present invention have experimentally confirmed that the compound exhibiting the MDH1 and/or MDH2 inhibitory activity has an inhibitory effect on mitochondrial respiration in cancer cells, an excellent inhibitory effect on cancer cell growth, etc. Thus, the compound of the present invention is expected to be effectively used as a pharmaceutical composition for treating cancer.

Embodiments and methods for a new class of potent non-peptidic covalent inhibitors of nsP2 cysteine protease that inhibit Venezuelan equine encephalitis virus's (VEEV) replication in neuroblasts are disclosed. More particularly, an acrylate and vinyl sulfone-based chemical series were investigated as promising starting scaffolds against VEEV and as inhibitors of the cysteine protease domain of VEEV's non-structural protein 2 (nsP2). The invention discloses compounds of Formula I and analogues for treatment of VEEV.
