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.

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.

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.

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.

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.

Structure-activity relationships and molecular modelling of 5-arylidene-2,4-thiazolidinediones active as aldose reductase inhibitors

The structure-activity relationships (SARs) of 5-arylidene-2,4- thiazolidinediones active as aldose reductase inhibitors (ARIs) were extended by varying the substitution pattern on the 5-arylidene moiety and on N-3. In particular, the introduction of an additional aromatic ring or an H-bond donor group on the 5-benzylidene ring enhanced ALR2 inhibitory potency. Moreover, the presence of a carboxylic anionic chain on N-3 was shown to be an important, although not essential, structural requisite to produce high levels of ALR2 inhibition. The length of this carboxylic chain was critical and acetic acids 4 were the most effective inhibitors among the tested derivatives. Molecular docking simulations into the ALR2 active site accorded with the in vitro inhibition data. They allowed the rationalization of the observed SARs and provided a pharmacophoric model for this class of ARIs.

Diabetes, a worldwide health concern while burdening significant populace of countries with time due to a hefty increase in both incidence and prevalence rates. Hyperglycemia has been buttressed both in clinical and experimental studies to modulate widespread molecular actions that effect macro and microvascular dysfunctions. Endothelial dysfunction, activation, inflammation, and endothelial barrier leakage are key factors contributing to vascular complications in diabetes, plus the development of diabetes-induced cardiovascular diseases. The recent increase in molecular, transcriptional, and clinical studies has brought a new scope to the understanding of molecular mechanisms and the therapeutic targets for endothelial dysfunction in diabetes. In this review, an attempt made to discuss up to date critical and emerging molecular signaling pathways involved in the pathophysiology of endothelial dysfunction and viable pharmacological management targets. Importantly, we exploit some Traditional Chinese Medicines (TCM)/TCM isolated bioactive compounds modulating effects on endothelial dysfunction in diabetes. Finally, clinical studies data on biomarkers and biochemical parameters involved in the assessment of the efficacy of treatment in vascular endothelial dysfunction in diabetes was compared between clinically used western hypoglycemic drugs and TCM formulas.

Aldose reductases influence prostaglandin F2alpha levels and adipocyte differentiation in male mouse and human species

Aldose reductases (AKR1B) are widely expressed oxidoreductases whose physiological function remains elusive. Some isoforms are genuine prostaglandin F2alpha (PGF2alpha) synthases, suggesting they might influence adipose homeostasis because PGF2alpha inhibits adipogenesis. This was shown by Akr1b7 gene ablation in the mouse, which resulted in increased adiposity related to a lower PGF2alpha content in fat. Yet humans have no ortholog gene for Akr1b7, so the role of aldose reductases in human adipose homeostasis remains to be explored. We analyzed expression of genes encoding human and mouse aldose reductase isoforms in adipose tissues and differentiating adipocytes to assess conserved mechanisms regulating PGF2alpha synthesis and adipogenesis. The Akr1b3 gene encoded the most abundant isoform in mouse adipose tissue, whereas Akr1b7 encoded the only isoform enriched in the stromal vascular fraction. Most mouse aldose reductase gene expression peaked in early adipogenesis of 3T3-L1 cells and diminished with differentiation. In contrast with its mouse ortholog Akr1b3, AKR1B1 expression increased throughout differentiation of human multipotent adipose-derived stem cells, paralleling PGF2alpha release, whereas PGF2alpha receptor (FP) levels collapsed in early differentiation. Pharmacological inhibition of aldose reductase using Statil altered PGF2alpha production and enhanced human multipotent adipose-derived stem adipocyte differentiation. As expected, the adipogenic effects of Statil were counteracted by an FP agonist (cloprostenol). Thus, in both species aldose reductase-dependent PGF2alpha production could be important in early differentiation to restrict adipogenesis. PGF2alpha antiadipogenic signaling could then be toned down through the FP receptor or aldose reductases down-regulation in human and mouse cells, respectively. Our data suggest that aldose reductase inhibitors could have obesogenic potential.

Intervention against the Maillard reaction in vivo

The field of Maillard/glycation reactions in vivo has grown enormously during the past 20 years, going from 25 to 500 publications per year. It is now well recognized that many of the “advanced” products form oxidatively or anaerobically and can have deleterious effects on macromolecular and biological function. The feasibility of developing pharmacological agents with beneficial in vivo properties, based on in vitro inhibition of glycation, has been surprisingly successful. This Editorial sets the stage for a series of articles by experts in the field, who have made key contributions to our understanding of the Maillard reaction in vivo.
