A series of N-aroylated isatins 1-15 was synthesized and evaluated for their antiglycation activity. All compounds showed a varying degree of glycation inhibitory activity with IC50 values between 18.01 ± 0.05-693.7 ± 3.0 μM, when compared with the standard (aminoguanidine) having an IC50 = 268.7 ± 12.4 μM. Compound 1 was found to be the most active member of this series with an IC50 = 18.01 ± 0.05

A series of novel 3-hydroxy-3-(2-imino-3-methyl-5-oxoimidazolidin-4-yl)indolin-2-one analogs (3) have been synthesized under microwave irradiation and conventional heating methods. These analogs were evaluated for in vitro cytotoxicity against a panel of 57 human tumor cell lines. Compound 3o had GI50 values of 190 nM and 750 nM against A549/ATTC non-small cell lung cancer and LOX IMVI melanoma cell

four of the human CA isoforms (hCA I, hCA II, hCA IX and hCA XII). All synthesized compounds were evaluated for their CA inhibitoryactivity. Most of the compounds preferentially inhibited the tumor-associated isoforms IX and XII. Series 9a-e and 10a-e showed the highest activity. Of particular interest was compound 10a which demonstrated the highest activity among all compounds with Ki of 68.3 and 21
Some new 1‐substituted isatin β‐thiosemicarbazones were examined for their ability to inhibit the growth of the wild‐type strain of vaccinia virus and the isatin P‐thiosemicarbazone (IBT) resistant mutant of this virus. Also investigated was the capability of the compounds to support the growth of the IBT dependent mutant of vaccinia virus. The most active derivative is 1‐(3‐hydroxypropyl)isatin thiosemicarbazone
