Substrate-induced up-regulation of aldose reductase by methylglyoxal, a reactive oxoaldehyde elevated in diabetes

Methylglyoxal (MG), a reactive dicarbonyl produced during glucose metabolism, induced a dose- and time-dependent increase in aldose reductase (AR) mRNA level in rat aortic smooth muscle cells (SMCs). AR has been implicated in the pathogenesis of diabetic complications, whereas the clinical efficacy of AR inhibitors has not been unequivocally proven. The enzyme catalyzes the reduction of glucose in the polyol pathway, as well as that of MG, which is known to be a preferred substrate of AR. A maximum of 4.5-fold induction of AR mRNA by MG was accompanied by elevated enzyme activity and protein levels and was completely abolished in the presence of cycloheximide or actinomycin D. Pretreatment of SMCs with N-acetyl-L-cysteine significantly suppressed the MG-induced AR expression, whereas DL-buthionine-(S,R)-sulfoximine further augmented the MG-induced increase in AR mRNA level. Intracellular levels of reactive oxygen species determined using 2?,7?-dichlorofluorescein diacetate were significantly elevated in SMCs treated with MG, suggesting the involvement of oxidative stress in this process. However, inconsistent with our previous findings on oxidative stress-induced up-regulation of AR, the inhibition of extracellular signal- regulated kinase by 2?-amino-3?-methoxyflavone (PD98059) did not affect MG-induced AR expression, whereas blockade of the p38 mitogen-activated protein kinase pathway by 4-(4-fluorophenyl)-2-(4-methylsulfonylphenyl)-5-(4-pyridyl) imidazol (SB203580) significantly suppressed the induction. The cytotoxic effect of MG on SMCs was significantly enhanced in the presence of the AR inhibitor ponalrestat, indicating a protective role of AR against MG-induced cell damage. Taken together, these observations indicated that substrate-induced induction of AR by MG during hyperglycemic conditions may hinder vascular remodeling and accelerate the development of vascular lesions in diabetes.

Potassium Salt of Fullerenylpenta-N-Dihydroxytyrosine Effects on Type 2 Diabetes Mellitus Therapeutic Targets

Abstract: It was shown for the first time that pentaamino acid derivative of fullerene C60 (potassium salt of fullerenylpenta-N-dihydroxytyrosine) affects three targets of type 2 diabetes mellitus. It competitively inhibits the enzymes aldose reductase and sorbitol dehydrogenase and also has an antiglycation effect on bovine serum albumin. The inhibition constants for these enzymes were calculated.

A non-invasive, multi-target approach to treat diabetic retinopathy

Hyperglycemia invoke number of pathways resulting in development of diabetic retinopathy (DR), including protein kinase C activation, increased expression of VEGF, advanced glycation end product (AGEs) formation and activation of polyol pathway, among which the pathophysiology of aldose reductase (ALR2) of the polyol pathway is evident by more than a decade of research. Subtle involvement of ALR2 in invoking various pathways of diabetic complications has caused an increase in attention towards the identification of novel aldose reductase inhibitors (ARIs). Numerous ARIs of different classes were employed in the treatment of diabetic complications initially, but few came into light as drugs. Though no ALR2 inhibitor has been used for the treatment or control of DR, Epalrestat has been used worldwide for treating diabetic neuropathy. This review critically analyses different treatments available for diabetic retinopathy, their limitations and the importance of the development of novel inhibitors of ALR2 that could prevent progression of DR, by causing a direct or indirect effect on controlling factors associated with DR.

Effects of diabetes on cholinergic transmission in two rat gut preparations

The gut may be a site of early diabetic neuropathy in humans and rats. The latter may provide appropriate models of these conditions. Therefore, cholinergic function was examined in two gut smooth muscle preparations from control, 30-day, and 6-month streptozotocin-diabetic and similarly diabetic rats that had received continuous treatment with an aldose reductase inhibitor, ponalrestat. Responses of terminal ileum longitudinal muscle to transmural nerve stimulation were depressed in preparations from untreated 30-day diabetic animals. Responses to exogenous acetylcholine were also depressed, by at least the same extent, in preparations from both 30-day and 6-month diabetic groups. Ponalrestat treatment prevented both changes in the 30-day study but did not prevent a depression of responses to acetylcholine in the 6-month study. Neither diabetes nor ponalrestat affected responses of esophageal muscularis mucosa to electrical stimulation or to exogenous acetylcholine. These observations suggest a change in the smooth muscle and/or noncholinergic innervation rather than in the cholinergic nerves of the ileal preparation. Cholinergic function in the ileum did not, therefore, seem to be an appropriate model of diabetic neuropathy.

Synthesis and antimycobacterial evaluation of novel phthalazin-4- ylacetamides against log- and starved phase cultures: Research article

Twenty four novel 2-[3-(4-bromo-2-fluorobenzyl)-4-oxo-3,4-dihydro-1- phthalazinyl]acetic acid amides were synthesized from phthalic anhydride and were subjected to in vitro and in vivo evaluation against log- and starved phase of mycobacterial species and Mycobacterium tuberculosis isocitrate lyase enzyme inhibition studies. Among the compounds screened, 2-(2-(4-bromo-2-fluorobenzyl) -1,2-dihydro-1-oxophthalazin-4-yl)-N-(2,6-dimethylphenyl)acetamide (5j) inhibited all eight mycobacterial species with MIC’s ranging from 0.08 to 5.05 mum and was non-toxic to Vero cells till 126.43 mum. Four compounds were tested against starved culture of Mycobacterium tuberculosis and they inhibited with MIC’s ranging from 3.78 to 23.2 mum. Some compounds showed 40-66% inhibition against Mycobacterium tuberculosis isocitrate lyase enzyme at 10 mum. The docking studies also confirmed the binding potential of the compounds at the isocitrate lyase active site. In the in vivo animal model, 5j reduced the mycobacterial load in lung and spleen tissues with 1.38 and 2.9-log10 protections, respectively, at 25 mg/kg body weight dose.

Initial evaluation of Cu-64 labeled PARPi-DOTA PET imaging in mice with mesothelioma

Poly(ADP-ribose) polymerase (PARP) has emerged as an important molecular target for the treatment of several oncological diseases. A couple of molecular probes based on Olaparib scaffold have been developed by incorporation of F-18 or fluorophore for positron emission tomography (PET) or optical imaging in several types of tumor. PARP has been reported overexpressed in mesothelioma. We hereby synthesized an analogue of Olaparib containing DOTA moiety and radiolabeled it with Cu-64 to evaluate its utility of PET tracer for mesothelioma. The Cu-64 labeling was conveniently achieved at 90% yield with final compound at >99% radiochemistry purity. The biodistribution and PET imaging were performed at 0.5, 1, 2 and 18?h to confirm the in vivo tumor targeting. The tumor uptake in study group was significant higher than that in control group (3.45?¡À?0.47% ID/g vs 2.26?¡À?0.30% ID/g) and tumor were clearly detected by PET imaging. These results suggest the feasibility to develop an Olaparib-based theranostic agent for mesothelioma.

Bioorthogonal approach to identify unsuspected drug targets in live cells

A proteomics method to pull down secondary drug targets from live cells is described. The drug of interest is modified with trans-cyclooctene (TCO) and incubated with live cells. Upon cell lysis, the modified drug bound to the protein is pulled down using magnetic beads decorated with a cleavable tetrazine-modified linker. Samples are then run on an SDS-PAGE gel and isolated bands are submitted for mass spectrometry analysis to identify drug targets. Copyright
