2-indolyl imidazo[4,5-d]phenanthroline compounds of Formula I that are capable of intracellular chelation of transition metals and of exerting antiproliferative effects in cancer cells, that are cytostatic and/or cytotoxic, are provided. Compounds of Formula I can also induce apoptosis in cancer cells and are thus capable of exerting a cytotoxic effect on cancer cells. The compounds of Formula I are also capable of selectively inhibiting the proliferation of one or more of prostate cancer cells, colon cancer cells, non-small lung cancer cells and leukemia cells. The compounds of Formula I are also capable of increasing the expression of the zinc-regulated tumour suppressor, KLF4 and thus are useful in inhibiting the proliferation of cancer cells in which KLF4 functions as a tumour-suppressor, including, but not limited to, bladder cancer, cancers of the gastrointestinal tract and various leukemias.
Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) Peroxodisulfate: A Mild and Efficient Oxidant for Cleavage of Nitrogen Double Bonds and Oxidation of Alcohols under Anhydrous Conditions
Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) peroxodisulfate (1), is readily prepared as an orange solid from commercially available 1,4-diazabicyclo[2.2.2]octane and potassium peroxodisulfate. This reagent easily converts hydrazones, semicarbazones, oximes, and alcohols to the corresponding carbonyl compounds with excellent yields.
(E)-3-[3-(pyridin-4-yl)-1-phenyl-1H-pyrazole-4-yl]acryl amides were evaluated for their antiplatelet activities. Compounds 4o and 4r were found as active derivatives showing a potent inhibitory activity on the arachidonic acid-induced aggregation, with IC50 of 20.2 and 30.3 mu M, respectively. Compounds 4j, 4k, and 4u presented significant inhibitor effect on collagen-induced platelet aggregation (73.1, 82.5, and 86.7 %, respectively). All synthesized compounds demonstrated good drug-likeness and drug-score values in silico evaluations.

months. In this study, various pyrazolic chalcone analogous compounds were synthesized and evaluated as potential chemotherapeutic agents for the treatment of hepatocellular carcinoma (HCC). Modifying the central pyrazole ring at the C(3)-position with different heteroaryl rings and substituting the C(4)-position of pyrazole with differently substitutedchalcone moiety produced fouthy two variant compounds
With the aim of achieving new compounds possessing both anti-inflammatory and antiplatelet activities, we synthesized (E)-3-[3-(pyridin-3/4-yl)-1-(phenyl/sulfonylmethylphenyl)-1H-pyrazol-4-yl]acrylamides, and evaluated their COX-1 and COX-2 inhibitory and antiplatelet activities. Since COX-2 inhibitory and antiplatelet compounds have anticancer potential, we also screened their antiproliferative effects
