R., once mentioned the application of 88150-47-4, Name is Amlodipine maleate, molecular formula is C24H29ClN2O9, molecular weight is 524.9481, MDL number is MFCD02259457, category is indole-building-block. Now introduce a scientific discovery about this category, Product Details of 88150-47-4.

Three metal-free organic D-pi-A dyes with benzothieno[3,2-b]indole as electron donor, cyanoacrylic acid as both electron acceptor and anchoring group with benzene (BID-1), thiophene (BID-2) and furan (BID-3) as pi-spacers were designed and synthesized for application in dye-sensitized solar cells (DSSCs). A planar and electron-rich heterocycle such as benzothieno[3,2-b]indole offers better backbone rigidity and improves charge transport properties in comparison to indolo[3,2-b]indole donor, previously reported from our group. Additionally, we synthesized a benzothieno[3,2-b]indole donor grafted with longer alkyl chains which efficiently prevented the approach of oxidized species in the electrolyte coming closer to semiconductor thereby arresting recombination. A power conversion efficiency of 4.11 % was achieved for dye-sensitized solar cells based on the furan pi-spacer benzothieno[3,2-b]indole dyeBID-3in comparison to the corresponding indolo[3,2-b]indole dye (IID-3) having an efficiency of 1.71 %. Detailed interfacial electrical measurements along with theoretical calculations disclosed the mechanism of back electron transfer and improvement in photovoltaic performance with respect to variation in both donor and pi-spacer.

Therefore, the development of new synthetic methods for the synthesis of indole derivatives is very popular. In this study, new oxindoles with reaction of 4,7-dihydro-1H-indole (2) and isatin (4) were synthesized as analogs of natural product 3,3′-bis(indolyl)oxindole. The biological properties of the compounds obtained during this study were also studied, showing that compounds 5, 7, and 12 inhibited the activity of G6PD with an IC50 of 99 mu M, 231 mu M, and 304 mu M respectively. The activity of rat erythrocyte 6PGD was increased in the presence of 5 and 7 and was inhibited in the presence of 12. As indole derivative 5 was an activator of 6PGD and inhibitor of G6PD, it was selected for docking studies to understand the mechanism of activation and inhibition.

Background: ZT55 is a novel natural product isolated from Radix isatidis. It is a highly-selective tyrosine kinase inhibitor against myeloproliferative neoplasms. Although earlier research has described the pharmacodynamic properties of ZT55 in vivo and in vitro, the quantitative determination and pharmacokinetic profile in vivo have not been thoroughly studied. Methods: A novel liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the quantification of ZT55 in rat plasma. A Waters symmetry C18 column was used for chromatographic separation; 0.1% formic acid in acetonitrile and 0.1% formic aqueous solution was used as the mobile phase. Detection was performed by Multiple Reaction Monitoring (MRM) mode using electrospray ionization in the positive ion mode. UPLC-QTOF-MS was used for the identification of metabolites. Results: The method was linear (R-2 =0.9988) over the concentration range of 1-2500 ng/mL. The lower limit of quantification was 1 ng/mL. The intra-day and inter-day precision of ZT55 showed a relative standard deviation within 8.47%, whereas the accuracy (RE) ranged from -4.84% to 4.45%. The recoveries ranged from 92.89% to 97.21%. ZT55 reached the highest plasma concentration at 0.5h. The peak concentrations with three dosages were 103.59 +/- 10.11, 185.23 +/- 29.56, and 355.98 +/- 28.86 ng/mL. The AUC(0-)(24) of three dosages were 874.70 +/- 72.33, 433.80 +/- 49.33, and 231.65++/- 19.41 ng.h/ml respectively. Five metabolites of ZT55 from plasma were confirmed. The main pathways of ZT55 in vivo were hydrolysis, N-dealkylation, glycosylation, and sulfonation. Conclusion: LC-MS/MS method was successfully applied to the pharmacokinetic study of ZT55 after oral administration and intravenous. ZT55 exhibited rapid oral absorption, high elimination, and low absolute bioavailability. This study provides important pharmacokinetic and metabolism information for further pharmacological and toxicological research on ZT55.
