Triptolide has been shown to exhibit anticancer activity. However, its mechanism of action is not clearly defined. Herein we report a novel signaling pathway, MDM2/Akt, is involved in the anticancer mechanism of triptolide. We observed that triptolide inhibits MDM2 expression in human breast cancer cells with either wild-type or mutant p53. This MDM2 inhibition resulted in decreased Akt activat...

Background Host defence peptide (HDP) has multiple properties [1,2] potentiating it as a novel anticancer agent. However disadvantages include systemic toxicity [3]. To address this, a prodrug was developed and the aim was to assess toxicity differentials between this prodrug and its active peptide component on T84 colonic carcinoma cells. Prodrug bio activation mechanism was also assessed by u...

Chalcones, or 1,3–diaryl–2–propen–1–ones, one of the major classes of natural products and posses many useful properties like anticancer, antibacterial, antifungal, anti–inflammatory, antimalarial and anti–diabetic activity. We report in this communication the synthesis and anticancer study of a number of novel chalcone sulfonamides. Our results indicate that the synthesis of chalcone sulfonami...

In recent years, researchers hunt for a novel anticancer agent mainly from plants. Phytochemicals and ubiquitous bioactive compound plays an important role in drug development. Among various phytochemicals, polyphenols have attracted considerable interest in the past few years due to their potential health benefits. One such phytochemical namely Coumarin (1,2-benzopyrone), a phenolic compound d...
