Abstract: The present invention relates to a nicotinohydrazide derivative, a stereoisomer thereof or a pharmaceutically acceptable salt thereof having a structure of formula (I): wherein each of X, Y and Z is one of N and CH, at least one of X, Y and Z is CH, at least one of X, Y and Z is N, and R is one of OH and NH2.

Abstract: The present invention provides novel pyrazolo[4,3-c]quinoline derivatives exhibiting specifically inhibition activity to microbiota ?-glucuronidase, whereby providing potent activities to prevent chemotherapy-induced diarrhea (CID) of cancers. Therefore, the compounds of the present invention can be used as (1) chemotherapy-adjuvant to prevent chemotherapy-induced diarrhea (CID) and enhance chemotherapeutic efficiency of cancers; (2) health-food supplement to prevent the carcinogens induced colon carcinoma.
