Structural tuning of acridones for developing anticancer agents targeting dihydrofolate reductase
摘要:
Targeting dihydrofolate reductase, here, we report the tumor growth inhibitory activity of substituted acridones. The screening of the molecules over 60 cell line panel of human cancer cells identified (S)-oxiran-2-ylmethyl 9-oxo-9,10-dihydroacridine-4-carboxylate (19) with average GI(50) 0.3 mu M. The specificity of the compound to CCRF-CEM, MOLT-4 and SR cell lines of leukemia and SW-620, SF268, LOXIMVI, ACHN and MCF7 cancerous cells exhibiting GI(50) in the nM range was observed. C6 Glioma cells treated with compound 19 showed differentiated cell morphology and cell cycle arrest in G2/M phase. The interactions of the compound with dihydrofolate reductase were ascertained with the help of enzyme immunoassays, molecular docking and molecular dynamic studies.
酪氨酸和10 H -acridin-9-a的拼接:在7.4-8.5的窄pH范围内开启荧光并在癌细胞内进行细胞内标记† •
摘要:
我们将10 H -acridin-9-one和(S)-酪氨酸修饰为3-(4-羟苯基)-2-[(9-氧代-9,10-二氢ac啶-4-羰基)氨基]丙酸(2) 。2经历了pH依赖的质子化/去质子化,并根据荧光的变化利用了该效应。分子在pH 7.5±1范围内的特征性荧光变化及其细胞渗透性使我们能够标记癌细胞。
The bioinspired design of a reagent allows the functionalization of C<sub>α</sub>–H of α,β-unsaturated carbonyl compounds via the Baylis–Hillman chemistry under ambient conditions
A rationally designed reagent capable to affect alkylation at C[small alpha] of [small alpha], [small beta]-unsaturated carbonylcompounds is reported. The reaction proceeded at room temperature without any additives. The pH and H-Bond...
