rapamycin-d-3

Rapamycin-d3 is the deuterium labeled Rapamycin. Rapamycin is a potent and specific inhibitor of mTOR(IC50 of 0.1 nM in HEK293 cells).

6-Hydroxypyridin-3-ylboronic acid is a heterocyclic building block.1,2It has been used in the synthesis of non-nucleoside inhibitors of hepatitis C virus (HCV) RNA-dependent RNA polymerase nonstructural protein 5B (NS5B).16-Hydroxypyridin-3-ylboronic acid has also been used in the synthesis of mammalian target of rapamycin (mTOR) inhibitors.2 1.Hendricks, R.T., Spencer, S.R., Blake, J.F., et al.3-Hydroxyisoquinolines as inhibitors of HCV NS5b RNA-dependent RNA polymeraseBioorg.

Arnicolide D is a sesquiterpene lactone. Arnicolide D isolates from Centipeda minima. Arnicolide D modulates the cell cycle, activates the caspase signaling pathway and inhibits the PI3K/AKT/mTOR and STAT3 signaling pathways. Arnicolide D inhibits Nasopharyngeal carcinoma (NPC) cell viability in a concentration- and time-dependent manner. Arnicolide D exerts strong cytotoxic activity on the human colon carcinoma HT-29 cell line.
