Two simple and validated chromatog. studies were performed for simultaneous estimation of sildenafil citrate (SIL) and alfuzosin hydrochloride (ALF) in bulk, pharmaceuticals, and in the presence of their main degradation products. Two systems of mobile phase were applied isocratically for their first chromatog. separation using conventional and micellar mobile phases. Methanol, acetonitrile, and 0.02 M potassium dihydrogen phosphate (43:14:43 volume/volume; pH 4.66) were pumped at 1.3 mL/min in method I. Meanwhile, method II was based on less hazardous micellar mobile phase of nonionic surfactant (0.005 M Brij-35 in water; pH 2.5 adjusted with 0.1% orthophosphoric acid) with a flow rate of 1 mL/min. Both methods were carried on C18 column and coupled with UV detection at 225 nm at ambient temperature The first method was rectilinear over the concentration range of 5-62.5 μg/mL for both drugs, while the second method showed higher linearity ranges of 0.5-40, 2.5-62.5 μg/mL for ALF and (SIL), resp. The developed methods successfully enabled the quantification of the studied binary mixture in their tablets dosage form and evaluation their stabilities. Validation of the proposed methods according to ICH guidelines and system suitability were ascertained. Moreover, the applied methods were evaluated and compared from the perspective of green anal. chem., employing the National Environmental Methods Index, anal. Eco-Scale score, and Green Anal.

Onder, Ferah Comert; Sahin, Kader; Senturk, Murat; Durdagi, Serdar; Ay, Mehmet published an article in 2022. The article was titled 《Identifying highly effective coumarin-based novel cholinesterase inhibitors by in silico and in vitro studies》, and you may find the article in Journal of Molecular Graphics & Modelling.Recommanded Product: 1-Methylpiperazine The information in the text is summarized as follows:

Inhibition of high cholinesterase levels including acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), is one of the most important strategies for the treatment of Alzheime′s disease (AD). Clin. limited drugs are used in the treatment of AD, so there is a need to find new effective inhibitors today. Therefore, in this study, synthesized six coumarin carboxamides (A1, A2, B1-B4) were evaluated against AChE and BChE by combined in silico and in vitro studies. The in vitro assessment of studied compounds revealed that A1, A2, B3, and B4 showed highest inhibition potential against AChE and BChE. As demonstrated with our structure activity relationship (SAR) study, the promising inhibition result of AChE at nanomolar concentrations was obtained with heterocyclic amines including pyrrolidine and N-Me piperazine moieties for tertiary amide substituted coumarin compounds B3 and B4, displaying KI values of 9.78 nM and 8.07 nM, resp. Thus, compounds B3 and B4 had around 5.7- and 6.9-fold more potency compared to the reference mol., neostigmine. Moreover, coumarin-3-carboxamide derivative A1 bearing benzylmorpholine moiety on coumarin scaffold at position 3 displayed stronger inhibition potential against BChE. Furthermore, in order to better understand their mol. mechanisms in these targets, we conducted mol. docking and MD simulations. Our promising preclin. results show that the lead compounds A1, A2, B3 and B4 have high potential as effective inhibitors for the treatment of AD. The experimental process involved the reaction of 1-Methylpiperazine(cas: 109-01-3Recommanded Product: 1-Methylpiperazine)

《Dopamine D4 receptor involvement in the discriminative stimulus effects in rats of LSD, but not the phenethylamine hallucinogen DOI》 was written by Marona-Lewicka, Danuta; Chemel, Benjamin R.; Nichols, David E.. COA of Formula: C17H19N5 And the article was included in Psychopharmacology (Berlin, Germany) on April 30 ,2009. The article conveys some information:

Rationale: Lysergic acid diethylamide (LSD) differs from other types of hallucinogens in that it possesses direct dopaminergic effects. The exact nature of this component has not been elucidated. Objective: The present study sought to characterize the effects of several dopamine D4 agonists and antagonists on the discriminative stimulus effect of LSD at two pretreatment times and 2,5-dimethoxy-4-iodoamphetamine (DOI), a selective 5-HT2A/2C agonist. Materials and methods: Male Sprague-Dawley rats were trained in a two-lever, fixed ratio (FR) 50, food-reinforced task with LSD-30 (0.08 mg/kg, i.p., 30-min pretreatment time), LSD-90 (0.16 mg/kg, i.p., 90-min pretreatment time), and DOI (0.4 mg/kg, i.p., 30-min pretreatment time) as discriminative stimuli. Substitution and combination tests with the dopamine D4 agonists, ABT-724 and WAY 100635, were performed in all groups. Combination tests were run using the dopamine D4 antagonists A-381393 and L-745,870 and two antipsychotic drugs, clozapine and olanzapine. Results: WAY 100635 produced full substitution in LSD-90 rats, partial substitution in LSD-30 rats, and saline appropriate responding in DOI-trained rats. ABT-724 partially mimicked the LSD-90 and LSD-30 cues, but produced no substitution in DOI-trained rats. In combination tests, both agonists shifted the dose-response curve of LSD leftward, most potently for the LSD-90 cue. The D4 antagonists significantly attenuated both the LSD-90 and LSD-30 cue, but had no effect on the DOI cue. Conclusion: Dopamine D4 receptor activation plays a significant modulatory role in the discriminative stimulus effects in LSD-90-trained rats, most markedly for the later temporal phase of LSD, but has no effect on the cue produced by DOI.Abt-724(cas: 70006-24-5COA of Formula: C17H19N5) was used in this study.

Abt-724(cas: 70006-24-5) belongs to piperazines. Piperazines are very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines.COA of Formula: C17H19N5

Formula: C5H12N2 The article mentions the following:

In this study, novel dithiocarbamate-sulfonamide derivatives I [R = Me, cyclohexyl, 4-O2NC6H4, etc.] were synthesized to investigate their inhibitory activity on purified human carbonic anhydrase (hCA) I and II. The IC50 and Ki values of the compounds were calculated to compare their inhibition profiles on hCA I and II isoenzymes. Acetazolamide was used as the standard inhibitor in the enzyme inhibition assay. Compounds I [R = Me, 4-MeC6H4CH2, CH2CH2NMe2, CH2CH2CH2NMe2, 2-pyridinyl, 2-pyrimidinyl] showed notable inhibitory effects against hCA I and II. Among these compounds, compound I [R = CH2CH2CH2NMe2] was found to be the most active derivate against both the hCA I and II enzymes with Ki values of 0.032 ± 0.001μM and 0.013 ± 0.0005μM, resp. The cytotoxicity of compounds I [R = Me, 4-MeC6H4CH2, CH2CH2NMe2, CH2CH2CH2NMe2, 2-pyridinyl, 2-pyrimidinyl] toward NIH/3T3 (mouse embryonic fibroblast cell line) was observed and the compounds were found to be non-cytotoxic. Furthermore, mol. docking studies were performed to investigate the interaction types between compound I [R = CH2CH2CH2NMe2] and the hCA I and II enzymes. As a result of this study a novel and potent class of CA inhibitors with good activity potential were identified. The experimental part of the paper was very detailed, including the reaction process of 1-Methylpiperazine(cas: 109-01-3Formula: C5H12N2)
