DC1 is an ADC cytotoxin, similar to the small groove-binding DNA alkylating agent CC-1065. DC1 can be used to synthesize antibody-drug conjugates targeted to the treatment of cancer. DC1Sme is a DC1 derivative with IC50 values of Ramos, Namalwa, HL60 / s
The extracellular signal-regulated kinase (ERK) signal transduction pathway regulates a diverse array of cellular processes. These processes include cell survival, proliferation, motility, and differentiation and are constitutively activated in cancers involving lung, colon, pancreas, kidney, and ovary. CAY10561 is a potent, ATP-competitive inhibitor of ERK2 (Ki = 2 nM). This compound is highly selective for ERK2 compared to other kinases such as PKA (Ki = 0.39 μM) and JNK3 (Ki = 4 μM). CAY10561 inhibits proliferation of COLO 205 cells with an IC50 value of 0.54 μM.
Pyracrenic acid is a potent elastase inhibitor with an IC50 value of 1.5 mg/mL. Pyracrenic acid shows DPPH radical scavenging activity. It also shows significant cytotoxic activities against human cancer cells COLO 205 and AGS.
Taiwanhomoflavone A is cytotoxic with ED50 values of 3.4, 1.0, 2.0 and 2.5 microg/ml, respectively, against KB epidermoid carcinoma of nasopharynx, COLO-205 colon carcinoma, Hepa-3B hepatoma, and Hela cervix tumor cells.
