《Design, Synthesis, and Molecular Modeling Studies of Novel Coumarin Carboxamide Derivatives as eEF-2K Inhibitors》 was published in Journal of Chemical Information and Modeling in 2020. These research results belong to Comert Onder, Ferah; Durdagi, Serdar; Sahin, Kader; Ozpolat, Bulent; Ay, Mehmet. HPLC of Formula: 109-01-3 The article mentions the following:

Eukaryotic elongation factor-2 kinase (eEF-2K) is an unusual alpha kinase commonly upregulated in various human cancers, including breast, pancreatic, lung, and brain tumors. We have demonstrated that eEF-2K is relevant to poor prognosis and shorter patient survival in breast and lung cancers and validated it as a mol. target using genetic methods in related in vivo tumor models. Although several eEF-2K inhibitors have been published, none of them have shown to be potent and specific enough for translation into clin. trials. Therefore, development of highly effective novel inhibitors targeting eEF-2K is needed for clin. applications. However, currently, the crystal structure of eEF-2K is not known, limiting the efforts for designing novel inhibitor compounds Therefore, using homol. modeling of eEF-2K, we designed and synthesized novel coumarin-3-carboxamides including compounds (I) and (II) and evaluated their activity by performing in silico anal. and in vitro biol. assays in breast cancer cells (structures contained within. The Mol. Mechanics/Generalized Born Surface Area (MM/GBSA) area results showed that I have interaction energies with eEF-2K better than those of II compounds Our in vitro results indicated that compounds I were highly effective in inhibiting eEF-2K at 1.0 and 2.5μM concentrations compared to compounds II, supporting the in silico findings. In conclusion, the results of this study suggest that our homol. modeling along with in silico anal. may be effectively used to design inhibitors for eEF-2K. Our newly synthesized compounds I may be used as novel eEF-2K inhibitors with potential therapeutic applications.1-Methylpiperazine(cas: 109-01-3HPLC of Formula: 109-01-3) was used in this study.

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.

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.

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. Procedure Index, as three assessment tools. The results came from multiple reactions, including the reaction of 1-Methylpiperazine(cas: 109-01-3Quality Control of 1-Methylpiperazine)

While neuroinflammation is an evolving concept and the cells involved and their functions are being defined, microglia are understood to be a key cellular mediator of brain injury and repair. The ability to measure microglial activity specifically and noninvasively would be a boon to the study of neuroinflammation, which is involved in a wide variety of neuropsychiatric disorders including traumatic brain injury, demyelinating disease, Alzheimer disease (AD), and Parkinson disease, among others. We have developed [11C]CPPC [5-cyano-N-(4-(4-[11C]methylpiperazin-1-yl)-2-(piperidin-1-yl)phenyl)furan-2-carboxamide], a positron-emitting, high-affinity ligand that is specific for the macrophage colony-stimulating factor 1 receptor (CSF1R), the expression of which is essentially restricted to microglia within brain. [11C]CPPC demonstrates high and specific brain uptake in a murine and nonhuman primate lipopolysaccharide model of neuroinflammation. It also shows specific and elevated uptake in a murine model of AD, exptl. allergic encephalomyelitis murine model of demyelination and in postmortem brain tissue of patients with AD. Radiation dosimetry in mice indicated [11C]CPPC to be safe for future human studies. [11C]CPPC can be synthesized in sufficient radiochem. yield, purity, and specific radioactivity and possesses binding specificity in relevant models that indicate potential for human PET imaging of CSF1R and the microglial component of neuroinflammation.
