Virtual screening: An effective tool for lead structure discovery?

Different methods of virtual screening as a tool for lead structure discovery are described. They range from structure based docking procedures to ligand based methods such as the chemical features based pharmacophore hypothesis approach. A review on several successful applications of virtual screening is given. Different approaches have been described to derive pharmacophore models, which were subsequently used for 3D database searching. The studies so far published cover a wide range of pharmacological applications. The results hereby obtained clearly indicate that focused assessment of corporate databases by virtual screening using well validated pharmacophore models yield to a significant improvement in lead structure determination compared to high throughput screening.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C17H12BrFN2O3, you can also check out more blogs about72702-95-5

Synthesis, biological, anti-inflammatory activities and quantum chemical calculation of some [4-(2, 4, 6-trimethylphenyl)-1(2H)-oxo-phthalazin-2yl] acetic acid hydrazide derivatives

The phthalazine carbohydrazide 2 was prepared and incorporated into the corresponding 1,2,4-triazole and carbamate derivatives. Phthalazine carboxylic acid hydrazide 2 was treated with isatine and cyclo-hexanone to give the corresponding hydrazone derivatives 16, 19 in good yields. Furthermore, alpha-amino acid derivative conjugated with 1-oxophthalazine moiety 35 was synthesized by the reaction of the corresponding aizde 28, via the azide-coupling method, with glycine methyl ester. The peptide ester 35 was converted into their corresponding amide 36 by treating with methanolic ammonia. Moreover, 35 was boiled with hydrazine hydrate to afford the corresponding hydrazide 37. Finally, the dipeptide 38 was prepared by coupling of 35 with L-alanine methyl ester. Some of these compounds were screened in vitro for their antimicrobial activity. The energy gap between the highest occupied molecular orbital and lowest unoccupied molecular orbital has been calculated using the theoretical computations to reflect the chemical reactivity and kinetic stability of compounds.

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.

Molecular modeling studies of aldose reductase inhibitors

Molecular modeling studies using the AM1 quantum chemical method and a torsional fitting method have been conducted on a series of aldose reductase inhibitors (ARIs) possessing an ionizable group and/or functional group susceptible to nucleophilic attack with the aim of defining the spatial position of ARI pharmacophores. AM1 quantum chemical calculations were conducted on ARIs possessing only an ionizable group to obtain their optimized geometries. These optimized structures were then superimposed on the model compound spirofluorene-9,5′-imidazolidine-2′,4′-dione (17). This superposition study suggests that a negative charge center residing in the vicinity of the 2′-oxygen of the imidazolidine-2′,4′-dione ring participates in the binding interactions. In addition, the optimized geometries of ARIs possessing both an ionizable group and an electronegative functional group were superimposed on spirofluorene-9,5′-imidazolidine-2′,4′-dione (17). The latter results also suggest the presence of a region where nucleophilic substitution can occur.

Novel, highly potent aldose reductase inhibitors: (R)-(-)-2-(4-bromo-2- fluorobenzyl)-1,2,3,4-tetrahydropyrrolo[1,2-alpha]pyrazine-4-spiro-3′- pyrrolidine-1,2′,3,5′-tetrone (AS-3201) and its congeners

A series of novel tetrahydropyrrolo[1,2-alpha]pyrazine derivatives were synthesized and evaluated as aldose reductase inhibitors (ARIs) on the basis of their abilities to inhibit porcine lens aldose reductase (AR) in vitro and to inhibit sorbitol accumulation in the sciatic nerve of streptozotocin- induced diabetic rats in vivo. Of these compounds, spirosuccinimide-fused tetrahydropyrrolo-[1,2-alpha]pyrazine-1,3-dione derivatives showed significantly potent AR inhibitory activity. In the in vivo activity of these derivatives, 2-(4-bromo-2-fluorobenzyl)-1,2,3,4-tetrahydropyrrolo-[1,2-alpha]pyrazine-4- spiro-3′-pyrrolidine-1,2′,3,5′-tetrone (23t) (SX-3030) showed the best oral activity. The enantiomers of 23t were synthesized, and the biological activities were evaluated. It was found that AR inhibitory activity resides in the (-)-enantiomer 43 (AS-3201), which was 10 times more potent in inhibition of the AR (IC50 = 1.5 x 10-8 M) and 500 times more potent in the in vivo activity (ED50 = 0.18 mg/kg/day for 5 days) than the corresponding (+)-enantiomer 44 (SX-3202). From these results, AS-3201 was selected as the candidate for clinical development. The absolute configuration of AS-3201 was also established to be (R)-form by single- crystal X, ray analysis. In this article we report the preparation and structure-activity relationship (SAR) of tetrahydropyrrolopyrazine derivatives including a novel ARI, AS-3201.
