Convenient and efficient synthesis of novel N-(4-acetyl-4,5-dihydro-5-(7,8,9-substituted-tetrazolo[1,5-a]-quinolin-4-yl)-1,3,4-thiadiazol-2-yl)acetamides 4a–j and their in vitro anticancer activity against two cell lines viz., human breast cancer cell line MCF7 and human cervix cancer cell line HeLa were carried out. GI50, LC50, TGI values were evaluated. Two of the compounds 4e and 4i with halogen substituent at 7th position of the target molecules have shown potent activity against human cervix cancer cell line HeLa. DNA cleavage studies revealed that most of these compounds show partial cleavage and few of them show complete cleavage of DNA. 相似文献

Coronary artery ectasia (CAE) is a well recognized clinical entity encountered during diagnostic cardiac catheterization. The etiopathogenesis of this condition is poorly understood. Due to the frequent presence of associated obstructive coronary artery disease it is considered to be a maladaptive process of atherosclerosis. Based on its association with aortic aneurysm, coronary ectasia is considered to be caused by genetic abnormalities. It is usually not a benign condition, as normal smooth laminar flow is disrupted with a potential of thrombus formation. The role of long-term anticoagulation in this condition has not been well established. It is speculated that with increasing use of newer, noninvasive modalities the incidence of ectasia may rise, therefore necessitating this review. 相似文献

Angiotensin converting enzyme (ACE) and α-amylase inhibitors were synthesized using 4′-(bromomethyl)-biphenyl-2-carbonitrile 1 and various cyclic secondary amines (a–h). The nitrile group appended to biphenyl was converted into tetrazole 3a–3h and the tetrazole was ring transformed into 1,3,4-oxadiazole derivatives 4a–4h. Some of the compounds have exhibited significant ACE and α-amylase inhibition. 相似文献

Effect of bischalcone derivative (2E,5E)-2,5-bis(4-hydroxy-3-methoxybenzylidene) cyclopentanone (CA) on blood glucose level and lipid profile was investigated in normoglycemic and streptozotocin (STZ)-induced diabetic rats. In oral glucose and sucrose tolerance test, treatment with CA (25 mg/kg) and glidenclamide (10 mg/kg) significantly improved the glucose and sucrose tolerance in normal animals. In addition, respective treatment for 7-day resulted in significant percentage reduction in serum glucose (SG). In standardized STZ-induced diabetic rats, a single dose of CA treatment exhibited reduction in SG levels at different time intervals compared to basal levels. The lipid profile levels are restored to near-normal value of all tested parameters. The compound CA was docked into the active site of 5′-AMP (adenosine monophosphate)-activated protein kinase (PDB ID: 2OOX). The binding and docking energy were found to be ?6.9 and ?45.1 kcal/mol, respectively. 相似文献
