Bioactivity

• In Vitro:
  A quantitative structure activity relationship (QSAR) model was developed by a forward stepwise multiple linear regression method to predict the activity of Withanolide Analogs against human breast cancer. The most effective QSAR model for anticancer activity against the SK-Br-3 cell showed the best correlation with activity (r2=0.93 and rCV2 =0.90). Similarly, cross-validation regression coefficient (rCV2=0.85) of the best QSAR model against the MCF7/BUS cells showed a high correlation (r2=0.91). In particular, compounds CID 73621, CID 435144, CID 301751 and CID 3372729 have a marked antiproliferative activity against the MCF7/BUS cells, while 2,3-dihydrowithaferin A-3-beta-O-sulfate, withanolide 5, Withanolide A, withaferin A, CID 10413139, CID 11294368, CID 53477765, CID 135887, CID 301751 and CID 3372729 have a high activity against the Sk-Br-3 cells compared to standard drugs 5-fluorouracil (5-FU) and camptothecin
