Abstract
BACKGROUND Previous and recent scientific research has shown that triazolopyrimidine and furochromones have a wide range of pharmacological activities for the treatment of numerous diseases, including anticancer, antiviral, anti-depressant, anti-microbial, anti-inflammatory, and analgesic activities. OBJECTIVE Preparation of new drugs derived from a natural furochromones as (1-hydrazinyl or methylthio),-furopyrimidoquinazolinone, 1, 2, 4-triazolopyrimidofuroquinazolin-5-one, and quinazoline- pyrimidofuro- quinazoline-8, 10-dione and the study of their biological activity as antimicrobial agents. METHODS A series of novel N'-furopyrimidoquinazoline-hydrazide; 1, 2, 4-triazolopyrimidofuroquinazolin- 5-one; furopyrimidoquinazolin-3-one and quinazoline-pyrimidofuroquinazoline-8, 10- dione derivatives were synthesized from substituted (methylthio)-furopyrimidoquinazolinone (3ab) and 1-hydrazinyl-furopyrimido- quinazolinone (4a-b) as the starting material. RESULTS All compounds were synthesized in good yields (71-95%) in a gradually efficient system under mild condition and some of the procedures were used such as microwave oven. The new compounds have been confirmed by means of different spectroscopic methods such as IR, 1D and 2D -NMR techniques and mass spectrum. The in vitro antimicrobial activities were evaluated for the prepared compounds using many types of bacteria (Gram-positive and Gram-negative) and fungi. CONCLUSION 1, 2, 4-triazolopyrimidofuroquinazolin-5-one derivatives (10a-f, 8a-b, 7a-b and 6a-d) showed the most efficient antimicrobial activities compared with the cefotaxime sodium and nystatin as standard drugs.

Abstract
Substituted-6-methyl-1-thioxo-1,2-dihydro-3H-furo[3,2-g]pyrimido[1,6-a]quinazolin-3-ones (5a,b) were synthesized from condensation of visnagenone (2a) or khellinone (2b) with 6-amino-thiouracil (3) in dimethylformamide or refluxing of (4a) or (4b) in dimethylformamide. Hence, compounds (5a,b) were used as the starting materials for preparing many new heterocyclic compounds such as; furo[3,2-g]pyrimido[1,6-a]quinazoline (6a,b), furo[3,2-g]thiazolo[2',3':2,3]pyrimido[1,6-a]quinazolinone (7a,b), substituted-benzylidene-furo[3,2-g]thiazolo[2',3':2,3]pyrimido[1,6-a]quinazoline-3,5-dione (8a⁻f), 3-oxo-furo[3,2-g]pyrimido[1,6-a]quinazoline-pentane-2,4-dione (9a,b), 1-(pyrazole)-furo[3,2-g]pyrimido[1,6-a]quinazolinone (10a,b), 2-(oxo or thioxo)-pyrimidine-furo[3,2-g]pyrimido[1,6-a]quinazolinone (11a⁻d), 1-(methylthio)-furo[3,2-g]pyrimido[1,6-a]quinazolinone (12a,b), 1-(methyl-sulfonyl)-furo[3,2-g]pyrimido[1,6-a]quinazolinone (13a,b) and 6-methyl-1-((piperazine) or morpholino)-3H-furo[3,2-g]pyrimido[1,6-a]quinazolin-3-one (14a⁻d). The structures of the prepared compounds were elucidated on the basis of spectral data (IR, ¹H-NMR, 13C-NMR, MS) and elemental analysis. Antimicrobial activity was evaluated for the synthesized compounds against Gram-positive, Gram-negative bacteria and fungi. The new compounds, furothiazolo pyrimido quinazolines 8a⁻f and 11a⁻d displayed results excellent for growth inhibition of bacteria and fungi.

Abstract
Furochromone derivatives are important synthetic targets which showed a myriad of interesting biological activities. Ammi visnaga (Umbelliferae) is the most famous source of these derivatives, which has been used in folk medicine for millennia targeting different ailments. Since the isolation of furochromone derivatives, different synthetic methodologies were developed for their preparation. Despite the recent interesting findings on this class of compounds, the chemical literatures lack a comprehensive summary on the synthetic methodologies and biological activities of furochromone derivatives. This review highlights recent advances in furochromones chemistry by discussing different synthetic procedures developed for the preparation of naturally occurring derivatives as well as other unique derivatives which showed promising biological activities. It also sheds light on the most common reactions of furochromone derivatives and the utilization of these derivatives as the blocks for many biologically active compounds.

Abstract
The inhibitory effects of nifedipine on renal vasoconstrictor response to angiotensin II, norepinephrine, or renal nerve stimulation were tested in anesthetized dogs. Intrarenal infusions of nifedipine (0.3, 1, and 3 micrograms/min) dose-dependently suppressed the renal vasoconstriction induced by intrarenal injections of angiotension II (0.03, 0.05, and 0.1 microgram) or norepinephrine (0.3-1 micrograms) but not that by renal nerve stimulation (4-7 Hz). However, the inhibitory effect of nifedipine on angiotensin II-induced vasoconstriction was greater than its effect on norepinephrine-induced or renal nerve stimulation-induced vasoconstriction (i.e., 50% reduction in renal blood flow). Furthermore, a greater renal vasodilation induced by intrarenal bolus injections of nifedipine (1,3, and 10 micrograms) but not by acetylcholine (0.1 and 0.3 microgram) was observed during the reduction in the perfusion pressure of the contralateral kidney to approximately 50 mm Hg, which resulted in an increase in plasma renin activity and plasma angiotensin II concentration but no change in plasma norepinephrine concentration. There was a significant positive correlation between plasma renin activity and plasma angiotensin II concentration before nifedipine injections and the subsequent increase in renal blood flow produced by each dose of nifedipine. These results indicate that nifedipine has a relatively preferential inhibitory effect on the renal vasoconstriction produced by both exogenous and endogenous angiotensin II in canine renal vasculature.

Abstract
Effects of the vasodilator dipyridamole (Dip) on plasma adenosine levels, heart rate, blood pressure and skin microcirculation were studied in 13 healthy male volunteers. Venous plasma concentrations of adenosine, catecholamines, dipyridamole and theophylline were determined by HPLC. Skin capillary blood cell velocity (CBV) was measured by videophotometric capillaroscopy in the finger nailfold. The adenosine uptake inhibitor Dip (approximately 1-3 microM in plasma) increased plasma adenosine from 0.15 +/- 0.03 to 0.29 +/- 0.03 microM (p less than 0.01) and heart rate (HR) by 13 +/- 2 beats/min (p less than 0.01) and reduced diastolic blood pressure by 6 +/- 2 mmHg (p less than 0.05). Dip did not significantly affect the skin circulation since basal CBV, digital pulse amplitude (DAPA), skin temperature and post-occlusive reactive hyperemia were unchanged. Plasma catecholamine levels were also unaffected. The adenosine receptor antagonist theophylline (45-55 microM in plasma) did not influence basal plasma catecholamine or adenosine levels, HR, blood pressure or skin microcirculation. Following theophylline Dip caused similar elevations of plasma adenosine but no changes in HR or blood pressures. Our results support the hypotheses that Dip dilates blood vessels in man by elevating endogenous adenosine and that theophylline acts as an adenosine antagonist. Under basal conditions, the skin microcirculation appears to be regulated mainly by factors other than adenosine.

Abstract
To determine the effects of the recently synthesized slow channel calcium blocker nitrendipine on systemic and regional hemodynamics, mean arterial pressure, heart rate, cardiac index and organ blood flow distribution were measured with the combined radioactive reference sample and microsphere techniques before and one hour after its oral administration (1 mg or 10 mg/kg). Twenty-week-old normotensive Wistar-Kyoto (WKY) and spontaneously hypertensive (SHR) conscious male rats were studied. At the 10 mg dose, nitrendipine exerted a hypotensive effect within 15 minutes, and this effect persisted throughout the study. After one hour, mean arterial pressure fell by 14 percent of pretreatment levels in WKY controls; it fell by 25 percent in SHR (p less than 0.001). This action was mediated by a fall in total peripheral resistance index (p less than 0.01) that was nonuniformly distributed to the organ circulations since blood flow was maintained or increased to brain, heart, kidneys, lungs, and adrenals, but decreased to skin. No change in cardiac index was observed.

Abstract
When nifedipine was given to rats at a dosage of 0.3 mg/kg, the blood pressure fell and heart rates rose slightly in normotensive controls, but both changes were more marked in rats with DOC-salt hypertension, the magnitude of the drop in mm Hg being progressively greater as hypertension evolved. Tachycardia also tended to increase, but became somewhat erratic once hypertension was established. Both changes were relatively constant and equivalent when expressed as a percentage of the initial value. Nifedipine given by minipump at a dosage of 8 mg/ml proved able to prevent or modulate, adrenal-regeneration hypertension, but not DOC-salt hypertension. However, in the latter, when the pumps were discontinued and a 1 mg/kg/day injection schedule was substituted, blood pressure fell in nifedipine-treated and rose in untreated rats. The latter dosage had a greater effect on blood pressure and heart rate of normotensive rats than 0.3 mg/kg.

Abstract
Trapidil inhibited the aggregation of rat platelets and the contraction of the isolated aortic strip of rabbit mainly caused by thromboxane A2, and the thromboxane A2 biosynthesis in rabbit platelets. The drug also reduced ischemic changes in ECG, the incidence of myocardial infarction, histopathological changes and a decrease in serum high density lipoprotein cholesterol, and inhibited an increase in plasma thromboxane B2 and a decrease in plasma 6-keto-prostaglandin F1 alpha content in the animals with an experimental ischemic heart injury caused by the injection of thromboxane A2 into the coronary artery. These findings suggest that trapidil is a new type of a therapeutic agent for ischemic heart disease which not only dilates the coronary artery but also inhibits the actions and biosynthesis of thromboxane A2 and may promote the biosynthesis of prostaglandin I2.

Abstract
Antihypertensive effects of nifedipine and hydralazine were investigated in normotensive rats, spontaneously hypertensive rats (SHR), DOCA-NaCl hypertensive rats and renal hypertensive rats all in a conscious state. The blood pressure fall after nifedipine 5 mg/kg p.o. was 22% of the initial value in normotensive rats, 49% in SHR, 53% in DOCA-NaCl hypertensive rats and 44% in renal hypertensive rats. Hydralazine in the same dose decreased the blood pressure by 40% in normotensive rats, 52% in SHR, 33% in DOCA-NaCl hypertensive rats and 54% in renal hypertensive rats. The selective action of nifedipine in hypertensive rats in contrast to normotensive rats seemed to be attributable to the different affinity for calcium ion of vascular smooth muscle of hypertensive rats as compared with that of normotensive rats. Also, the heart rate of hypertensive rats or normotensive rats was increased with nifedipine but less than with hydralazine.

Abstract
The effects of the calcium-antagonist nifedipine on atrioventricular (A-V) conduction and blood flow were investigated in comparison with those of verapamil by the use of the isolated, arterially blood-perfused A-V node preparation of the dog. Single injections of 0.3--30 mug of nifedipine and verapamil into the A-V node artery produced a dose-related increase in the A-V conduction time and at 30 mug the two drugs caused second degree block of A-V conduction. The results are compatible with the hypothesis that a slow calcium channel plays an important role in excitation of A-V nodal cells. The rate of blood flow through the A-V node artery was about 10 times more sensitive to nifedipine than was the A-V conduction time and increased in a dose-related manner. In contrast, an increase in blood flow rate by verapamil occurred in almost the same dose range as did impairment of A-V conduction. This indicates that the action of nifedipine is more pronounced on coronary smooth muscle cells than on the A-V nodal cells.
