New Substituted C(14)-andrographolide Derivatives with Potent Cytotoxic Activities
نویسنده
چکیده
Andrographolde is the major secondary metabolite from the plant Andrographis paniculata. It has been found to show cytotoxic activity. To improve the efficacy on cytotoxic activity, a series of new sulfonyl derivatives have been synthesized by structural modifications of the andrographolide at C-2 position. All the derivatives were tested for their cytotoxic activity against human small lung cancer (NCI-H187), leukemia K562, breast cancer (MCF-7/ADR) and lung adenocarcinoma (A549) cell lines. Most of the compounds have appreciable activity at tested cell lines. Compound 4a exhibited higher cytotoxic activity than parent compound andrographolide.

A number of N-arylmethyl substituted indole derivatives have been synthesized and their effectiveness against ADP and arachidonic acid induced platelet aggregation in human plasma was determined. The desired compounds were synthesized by reacting the appropriate aniline derivative with isatin (or substituted isatin) to form the corresponding imine structures. The so formed compound was then act...
