mutants, Est816-M3 and Est816-M4, successfully overcame and even reversed the low enantioselectivity, and several 2-arylpropionicacidderivatives with high E values were obtained. Our results offer potential industrial biocatalysts for the preparation of structurally diverse chiral carboxylic acids and further lay the foundation for improving the catalytic efficiency and enantioselectivity of esterases.
Described are compositions and methods for treating cancer. Some methods comprise the administration of an effective amount of at least one inhibitor of tryptophan 2,3-dioxygenase (TDO) and/or indoleamine 2,3-dioxygenase (IDO), optionally combined with one or more additional anti-cancer agents.

Optical isomers of phenylpropionic acid drugs are a mixture having R-type optical isomer and S-type optical isomer at a ratio of 10:1-1:10 by weight, wherein the ratio of 1:1 is excluded. A use of the optical isomers includes that the R-type optical isomer is used for manufacturing anti-inflammatory and analgesic drugs and the mixture having the R-type optical isomer and the S-type optical isomer at a ratio of 10:1-1:10 by weight, wherein the ratio of 1:1 is excluded, is used for manufacturing anti-inflammatory and analgesic drugs. The therapeutic indexes of anti-inflammatory and analgesic drugs of the present optical isomers are all higher than those of the S-type optical isomers and the racemate.
