Application of 72702-95-5, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 72702-95-5, 2-(3-(4-Bromo-2-fluorobenzyl)-4-oxo-3,4-dihydrophthalazin-1-yl)acetic acid, introducing its new discovery.
Reduction of glomerular hyperfunction during short-term aldose reductase inhibition in normoalbuminuric, insulin-dependent diabetic patients
In experimental diabetes, functional and structural abnormalities in kidneys, nerves and retina have been associated with enhanced metabolism through the polyol pathway. In normoalbuminuric, insulin-dependent diabetic patients we have previously demonstrated a reduction in glomerular hyperfiltration during 6 months of aldose reductase inhibition with ponalrestat. To investigate this effect further, a study with administration of ponalrestat (600 mg daily) or placebo for 14 days was performed. In the eight patients treated with ponalrestat, glomerular filtration rate (GFR) (clearance of 125I-iothalamate) was promptly reduced from 131 ¡À 5 on day 0 (mean ¡À SEM) to 118 ¡À 4 on day 3 (P<0.01 vs day 0) and 116 ¡À 4 ml/min/1.73 m2 on day 14 (P<0.005 vs day 0: i1 paired t-test). No significant change in GFR was seen in the six patients treated with placebo (GFR: 142 ¡À 6,140 ¡À 4, 140 ¡À 6 ml/min/1.73 m2). Renal plasma flow (clearance of 131I-hippuran) decreased during ponalrestat treatment (529 ¡À 23, 483 ¡À 20, 477 ¡À 21 ml/min/1.73 m2, P<0.005 day 0 vs 3, P = 0.06 day 0 vs 14), whereas no significant change was seen during placebo (655 ¡À 41,617 ¡À 17, 631 ¡À 36 ml/min/1.73 m2). Peripheral and autonomic nerve function was assessed on day 0 and 14. No change was seen in vibration perception threshold on two locations. Minimal resting heart rate during deep breathing declined (ponalrestat: 55.3 ¡À 2.g vs 51.5 ¡À 2.2, P<0.01; placebo 53.5 ¡À 2.1 vs 54.5 ¡À 4.5, n.s.), while no significant change was noted in beat to beat variation (ponalrestat: 21.1 ¡À 3.0 vs 22.0 ¡À 3.6; placebo: 21.2 ¡À 2.9 vs 21.5 ¡À 5.0). Orthostatic blood pressure test was unaltered in both study groups. In conclusion, inhibition of increased polyol pathway activity by ponalrestat, 'acutely' (? 3 days) caused a marked reduction in glomerular hyperfiltration in normoalbuminuric IDDM patients. A metabolic effect on parasympathetic nerve function is also suggested. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 72702-95-5.
