One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 591-11-7, Name is 5-Methylfuran-2(5H)-one, formurla is C5H6O2.

Novel oxindole/benzofuran hybrids as potential dual CDK2/GSK-3 beta inhibitors targeting breast cancer: design, synthesis, biological evaluation, and in silico studies
The serine/threonine protein kinases CDK2 and GSK-3 beta are key oncotargets in breast cancer cell lines, therefore, in the present study three series of oxindole-benzofuran hybrids were designed and synthesised as dual CDK2/GSK-3 beta inhibitors targeting breast cancer (5a-g, 7a-h, and 13a-b). The N-1 -unsubstituted oxindole derivatives, series 5, showed moderate to potent activity on both MCF-7 and T-47D breast cancer cell lines. Compounds 5d-f showed the most potent cytotoxic activity with IC50 of 3.41, 3.45 and 2.27 mu M, respectively, on MCF-7 and of 3.82, 4.53 and 7.80 mu M, respectively, on T-47D cell lines, in comparison to the used reference standard (staurosporine) IC50 of 4.81 and 4.34 mu M, respectively. On the other hand, the N-1-substituted oxindole derivatives, series 7 and 13, showed moderate to weak cytotoxic activity on both breast cancer cell lines. CDK2 and GSK-3 beta enzyme inhibition assay of series 5 revealed that compounds 5d and 5f are showing potent dual CDK2/GSK-3 beta inhibitory activity with IC50 of 37.77 and 52.75 nM, respectively, on CDK2 and 32.09 and 40.13 nM, respectively, on GSK-3 beta. The most potent compounds 5d-f caused cell cycle arrest in the G2/M phase in MCF-7 cells inducing cell apoptosis because of the CDK2/GSK-3 beta inhibition. Molecular docking studies showed that the newly synthesised N-1-unsubstituted oxindole hybrids have comparable binding patterns in both CDK2 and GSK-3 beta. The oxindole ring is accommodated in the hinge region interacting through hydrogen bonding with the backbone CO and NH of the key amino acids Glu81 and Leu83, respectively, in CDK2 and Asp133 and Val135, respectively, in GSK-3 beta. Whereas, in series 7 and 13, the N-1-substitutions on the oxindole nucleus hinder the compounds from achieving these key interactions with hinge region amino acids what rationalises their moderate to low anti-proliferative activity.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 591-11-7 help many people in the next few years. Product Details of 591-11-7.
