3-Aroyl-1,4-diarylpyrroles Inhibit Chronic Myeloid Leukemia Cell Growth through an Interaction with Tubulin
摘要:
We designed 3-aroyl-1,4-diarylpyrrole (ARDAP) derivatives as potential anticancer agents having different substituents at the 1- or 4 -phenyl ring. ARDAP compounds exhibited potent inhibition of tubulin polymerization, binding of colchicine to tubulin, and cancer cell growth. ARDAP derivative 10 inhibited the proliferation of BCR/ABL-expressing KU812 and LAMA84 cells from chronic myeloid leukemia (CML) patients in blast crisis and of hematopoietic cells ectopically expressing the imatinib mesylate (IM) -sensitive KBM5-WT or its IM -resistant KBM5-T315I mutation. Compound 10 minimally affected the proliferation of normal blood cells, indicating that it may be a promising agent to overcome broad tyrosine kinase inhibitor resistance in relapsed/refractory CML patients. Compound 10 significantly decreased CML proliferation by inducing G2/M phase arrest and apoptosis via a mitochondria-dependent pathway. ARDAP 10 augmented the cytotoxic effects of IM in human CML cells. Compound 10 represents a robust lead compound to develop tubulin inhibitors with potential as novel treatments for CML.
A large series of chalcones were synthesized and studied against Staphylococcus aureus and Escherichia coli. Chalcones were either unsubstituted in ring A or possessed 4-chloro or 3',4',5'-trimethoxy groups. Their other ring B was variously substituted. It was found that the antistaphylococcal activity of chalcones was related to the energy difference between the two highest occupied molecular orbitals (HOMO and HOMO-1). Presence of hydroxyl group in ring B was not a determinant factor for the anti-staphylococcal activity, but the lipophilicity of ring A of the hydroxyl chalcones was of importance.

Identification of 3′,4′,5′-trimethoxychalcone analogues as potent inhibitors of Helicobacter pylori-induced inflammation in human gastric epithelial cells
Efforts to identify potent small molecule inhibitors of Helicobacter pylori led to the evaluation of 23 3',4',5'-trimethoxychalcone analogues. Some of the compounds displayed potent antibacterial activity against H. pylori. Three most active and selective compounds 1, 7, and 13 also showed the bactericide activity against the reference as well as multidrug-resistant strains of H. pylori. Additionally, the aforementioned three compounds potentially inhibited the H. pylori adhesion and invasion to human gastric epithelial (AGS) cells. Furthermore, these selective compounds inhibited the H. pylori-induced gastric inflammation by reduced inflammatory mediator's nuclear factor kappa B activation, and the secretion of interleukin-8.

3‐Arylindanones and related compounds as antiproliferative agents against colorectal cancer
derivatives were synthesized as anticancer agents. Two of the analogues, that is 7 and 22, exhibited significant antiproliferative activity against several human cancer cell lines. Both the compounds possessed antimitotic activity and induced apoptosis in DLD1 colorectal adenocarcinoma cells through activation of caspase pathways. In cell cycle analysis, both the compounds induced predominantly G2/M phase arrest
