Accumulation of age-associated senescent cells accompanied with increased reactive oxygen species (ROS) and inflammatory factors contributes to the progression of age-related macular degeneration (AMD), the main cause of blindness in the elderly. Berberine (BBR) has shown efficacy in the treatment of age-related diseases including diabetes and obesity by decreasing ROS. However, the pharmacol. effect of BBR on alleviating retinal aging remains largely unknown. Our study aimed to investigate the pharmacol. effect of BBR as an anti-aging agent in retinal aging and its further mol. mechanisms. D-galactose (DG)-induced ARPE-19 cell senescence and retinal aging were employed to evaluate the anti-aging effect of BBR in vivo and in vitro. The siRNA transfection, Western-Blot analyses, SA-β-Gal assay and immunofluorescence were performed to investigate the potential mechanisms of BBR on anti-aging of RPE. In RPE-choroid of both natural aged and DG-induced accelerated aged mice, oxidative stress was increased along with the up-regulation of p21 expression, which was ameliorated by BBR treatment. BBR down-regulated the expression of REDD1 to decrease intracellular ROS content, attenuating DG-induced senescence in vitro and in vivo. Furthermore, p53 instead of HIF-1α was identified as the transcriptional regulator of REDD1 in DG-induced premature senescence. Importantly, NAC and BBR reversed the expression of p53 and the content of 8-OHdG, indicating that the pos. feedback loop of ROS-DNA damage response (DDR) was formed, and BBR interrupted this feedback loop to alleviate DG-induced premature senescence by reducing REDD1 expression. In addition, BBR restored DG-damaged autophagy flux by up-regulating TFEB-mediated lysosomal biosynthesis by inhibiting REDD1 expression, thereby attenuating cellular senescence. BBR down-regulates REDD1 expression to interrupt the ROS-DDR pos. feedback loop and restore autophagic flux, thereby reducing premature senescence of RPE. Our findings elucidate the promising effects of REDD1 on cellular senescence and the great potential of BBR as a therapeutic approach. In the experiment, the researchers used many compounds, for example, 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium (cas: 2086-83-1Category: isoquinoline).

Being an analog of pyridine, isoquinoline is a weak base, with a pKa of 5.14. The Pomeranz–Fritsch reaction provides a method for the preparation of isoquinoline. This reaction uses a benzaldehyde and aminoacetoaldehyde diethyl acetal, which in an acid medium react to form isoquinoline.Category: isoquinoline

Solifenacin/mirabegron induces an acute compliance increase in the filling phase of the capacity-reduced urinary bladder: a pressure-volume analysis in rats was written by Peng, Hsien-Yu;Lai, Cheng-Yuan;Hsieh, Ming-Chun;Lin, Tzer-Bin. And the article was included in Frontiers in Pharmacology in 2021.Category: isoquinoline This article mentions the following:

Pressure in the bladder, which is a high compliance organ, is only slightly elevated to a considerable filling volume during storage. Although cystometry off-line offers mean compliance, no protocol is available for real-time assays of the dynamics of bladder compliance, and the potential impact of solifenacin and mirabegron on dynamic bladder compliance has not been established. Along with constantly infused cystometry, a pressure-volume anal. (PVA) was performed by plotting intra-vesical volume against pressure in Sprague-Dawley rats. The instant compliance was assayed as the slope of the trajectory, and the mean compliance (Cm) was determined by the slope of the line produced by regression of the data points at the end of the first, second, and third quarters of the filling phase. Under a steady-state, the PVA trajectory moved clockwise which shaped coincident enclosed loops with stable compliance. Though administering to naive animals solifenacin, but not mirabegron (both 1 × 10^-5-1 × 10^-1 mg/kg, i.a.) decreased the peak pressure, both of these reagents exhibited acute increments in the trajectory slope and Cm of the filling phase in a dose-dependent manner (ED₅₀ = 1.4 × 10-4 and 2.2 × 10^-5 mg/kg, resp.). Resembling urine frequency/urgency in OAB patients, the voiding frequency of a capacity-reduced bladder was increased in association with decreased compliance which was ameliorated by both acute solifenacin and mirabegron injections (both 1 × 10^-1 mg/kg). In addition to their well-known anti-inotropic/relaxative effects, solifenacin, and mirabegron induce an acute increase in bladder compliance to ameliorate OAB-like syndromes. Together with time-domain cystometry, PVA offers a platform for investigating the physiol./pathophysiol./pharmacol. of bladder compliance which is crucial for urine storage. In the experiment, the researchers used many compounds, for example, (S)-(R)-Quinuclidin-3-yl 1-phenyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (cas: 242478-37-1Category: isoquinoline).

Electrophotocatalytic Decarboxylative C-H Functionalization of Heteroarenes was written by Lai, Xiao-Li;Shu, Xiao-Min;Song, Jinshuai;Xu, Hai-Chao. And the article was included in Angewandte Chemie, International Edition in 2020.Related Products of 27104-73-0 This article mentions the following:

Decarboxylative C-H functionalization reactions are highly attractive methods for forging carbon-carbon bonds considering their inherent step- and atom-economical features and the pervasiveness of carboxylic acids and C-H bonds. An ideal approach to achieve these dehydrogenative transformations is through hydrogen evolution without using any chem. oxidants. However, effective couplings by decarboxylative carbon-carbon bond formation with proton reduction remain an unsolved challenge. Herein, the authors report an electrophotocatalytic approach that merges organic electrochem. with photocatalysis to achieve the efficient direct decarboxylative C-H alkylation and carbamoylation of heteroaromatic compounds through hydrogen evolution. This electrophotocatalytic method, which combines the high efficiency and selectivity of photocatalysis in promoting decarboxylation with the superiority of electrochem. in effecting proton reduction, enables the efficient coupling of a wide range of heteroaromatic bases with a variety of carboxylic acids and oxamic acids. Advantageously, this method is scalable to decagram amounts, and applicable to the late-stage functionalization of drug mols.

Nine isoquinoline Rho kinase inhibitors were designed and synthesized on the basis of a ligand-binding pocket model. With fasudil, the only Rho kinase inhibitor marketed to date, as a reference compound, their biol. activities were determined, including assays of Rho kinase inhibitory activity, synapse formation, cell viability. Bio-assays were performed by means of MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays and lactate dehydrogenase (LDH) assays. The obtained results indicated that (R)-6H-1-(5-isoquinolinesulfonyl)-2-hydroxy methyl-1-pyrrolidine and (R)-6H-1-(5-isoquinolinesulfonyl)-2-chloromethyl-1-pyrrolidine exhibited excellent Rho kinase inhibitory activity, deactivation of Rho kinase led to accelerated synapse formation and enhanced cell viability. Therefore they might be potential candidates for preventing various neurol. disorders. The brief study on the structure-activity relationship of these isoquinoline analogs demonstrated that modification of inhibitors targeting region D of the Rho kinase binding pocket is quite efficacious, the existence of free amino, chloro- or hydroxyl group as binding sites with region D of Rho kinase is necessary for increasing the inhibitory activity.

Nevertheless, the holistic therapeutic mechanism of SGC in vivo remain poorly interpreted. To systematically explore the preventive effect and mechanism of SGC on CHD rats using plasma metabolomics strategy. Rat CHD model was established by left anterior descending coronary artery ligation (LAD). Echocardiog, histol. analyses of the myocardium and biochem. assays on serum were used to confirm the successful establishment of the CHD model and therapeutic effects of SGC. Then, UHPLC-MS/MS-based plasma metabolomics was combined with multivariate data anal. to screen potential pharmaco biomarkers associated with SGC treatment in the LAD-induced rat CHD model.
