In this study, novel condensed 1,4-dihydropyridines bearing cyclopentanone (1-21) or tetrahydrothiophene-1,1-dioxide ring (22-42) with various ester substituents were synthesized via a modified Hantzsch reaction and their calcium channel modulator activities were investigated on isolated rat ileum and rat thoracic aorta. The introduction of a cyclopentanone ring fused to the 1,4-dihydropyridine...
New quinazoline derivatives were prepared by one pot reaction of anthranilic acid, acetic anhydride and primary amines, under ultrasonic irradiation. As a result, Ultrasonic irradiation has led to affordable, clean synthesis of a variety of target compounds in much higher yields, than traditional methods. This method has numerous advantages: such as higher yields, shorter reactions time, and ea...

Pioglitazone is a widely used anti-type 2 diabetic drug. Beside its insulin-sensitizing effects, pioglitazone exerts preventive roles against ischemic heart disease. Since one possible explanation is anti-hypertensive action, we examined effects of pioglitazone on contractility of isolated blood vessel. Endothelium-intact [End (+)] or -removed [End (-)] rat aorta is isolated and isometric tensi...
Hispidacine, an 8,4'-oxyneolignan featuring incorporation of an unusual 2-hydroxyethylamine moiety at C-7, and hispiloscine, a phenanthroindolizidine alkaloid, were isolated from the stem-bark and leaves of the Malaysian Ficus hispida Linn. Their structures were established by spectroscopic analysis. Hispidacine induced a moderate vasorelaxant activity in rat isolated aorta, while hispiloscine ...
A new bisbenzylisoquinoline, lancifoliaine (1), together with seven known alkaloids--N-allyllaurolitsine (2), reticuline (3), actinodaphnine, norboldine, pallidine, cassythicine and boldine--were isolated from the stem bark of Litsea lancifolia (Lauraceae). In addition to that of lancifoliaine, complete ¹³C-NMR data of N-allyl-laurolitsine (2) was also reported. The alkaloidal structures were e...
Objective(s): The study aimed to investigate the effects of adrenomedullin (ADM) and proadrenomedullin N- terminal 20 peptide (PAMP) on angiotensin II (AngII)-stimulated proliferation in vascular smooth muscle cells (VSMCs). Materials and Methods: Thoracic aorta was obtained from Wistar rats and VSMCs were isolated from aorta tissues and then cultured. In vitro cultured VSMCs were stimulated w...
