Pharmaceutical formulations include the organic compounds or pharmaceutically acceptable salts thereof and a pharmaceutically acceptable carrier and may be prepared by mixing the organic compounds or pharmaceutically acceptable salts of the organic compounds with a carrier and water. A method of treating a patient includes administering a pharmaceutical formulation according to the invention to a patient in need thereof.
Compounds of Structure I, and salts, tautomers, stereoisomers, and mixtures thereof may be used in methods of inhibiting checkpoint kinase 1 in subjects, in methods for inducing cell cycle progression, and in methods for increasing apoptosis in cells. Such compounds may be used to prepare pharmaceutical compositions and may be used in conjunction with DNA damaging agents.

yielding IC50 values of 6–60 μM for three unsubstituted metal-free ligands, whereas values for the metal complexes vary in a broad range from 0.3 to 140 μM. Complexation with osmium of quinoxalinone derivatives with benzimidazole or benzothiazole results in a more consistent increase in cytotoxicity than complexation with ruthenium. For selected compounds, the capacity to induce apoptosis was confirmed
已合成了一系列具有 3-(1 H-苯并咪唑-2-基)-1 H-喹喔啉-2-one 的钌 (II) 芳烃配合物,具有已知蛋白激酶抑制剂的药效基团,以及相关的苯并恶唑和苯并噻唑衍生物. 此外,还制备了相应的未取代配体的锇配合物。这些化合物已通过 NMR、UV-vis 和 IR 光谱、ESI 质谱、元素分析和 X 射线晶体学进行了表征。通过 MTT 测定法测定三种人类癌细胞系(A549、CH1、SW480)的抗增殖活性,产生 IC 50三个未取代的无金属配体的值为 6-60 μM,而金属配合物的值在 0.3 至 140 μM 的宽范围内变化。与苯并咪唑或苯并噻唑与喹喔啉酮衍生物的锇络合导致比与钌络合更一致地增加细胞毒性。对于选定的化合物,通过荧光显微镜和流式细胞术分析证实了诱导细胞凋亡的能力,而细胞周期效应只是中等的。
