New Substituted Isocoumarins and Dihydroisocoumarins and their Cytotoxic Activities
New isocoumarins were prepared in an efficient way from 2-iodobenzoic acid derivatives and hept-1-yne in a Sonogashira reaction, followed by spontaneous cyclization. Catalytic hydrogenation gave the corresponding dihydroisocoumarins. A 4-chloroisocoumarin was prepared on an alternative pathway. Some of the new compounds showed moderate cytotoxic activities against a human leukemia cell line (HL...
متن کاملShort Approach Towards New Isocoumarins and Dihydroisocoumarins and Investigation of their Cytotoxic Activities
Isocoumarins are a large and structurally diverse class of bioactive natural products with widespread occurance in living organisms [1], and considerable work has been published over decades about their chemistry [2] and biology [3]. A considerable number of natural and synthetic isocoumarins showed significant cytotoxic and antitumor activity. Among those are dihydroisocoumarins like AI-77-B (...
متن کاملNew Substituted C(14)-andrographolide Derivatives with Potent Cytotoxic Activities
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 ca...
متن کاملNew Diphenol and Isocoumarins from the Aerial Part of Lawsonia inermis and Their Inhibitory Activities against NO Production.
Lawsonia inermis Linn (Lythraceae), also known as henna, is a small shrub or tree distributed throughout Taiwan's Lanyu Island, in North Africa, and in Australia. Its leaves are used as a folk medicine for the treatment of external hemorrhage and fingernail abscesses. Investigation of the ethyl acetate (EtOAc)-soluble fractions from methanol extract of the aerial part of Lawsonia inermis has le...
متن کاملDocking Studies, Synthesis, Characterization and Evaluation of Their Antioxidant and Cytotoxic Activities of Some Novel Isoxazole-Substituted 9-Anilinoacridine Derivatives
A convenient synthesis of novel isoxazole-substituted 9-anilinoacridine derivatives 5a-j was reported. The compounds were confirmed by physical and analytical data and screened for in vitro antioxidant activity by DPPH method, reducing power assay and total antioxidant capacity method. The cytotoxic activity of the compounds was also studied in HEp-2 cell line. The docking studies of the synthe...
