DBDA as a Novel Matrix for the Analyses of Small Molecules and Quantification of Fatty Acids by Negative Ion MALDI-TOF MS
Matrix interference ions in low mass range has always been a concern when using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to analyze small molecules (500 Da). In this work, a novel matrix, N1,N4-dibenzyli
Computer-aided design, synthesis, and biological studies of anticological nitrogen-containing tetraphosphonic acids against melanoma
Abstract: As a part of our quest to develop new bioactive bisphosphonic acids, we synthesized a series of bis(α-aminobisphosphonic acids) in good yields (66–78%) as new entities for treating malignant melanoma. The reaction of the Schiff bases, 1,4-pheney

Novel bridgehead nitrogen bisheterocyclic systems: Synthesis, stereochemistry and antimicrobial activity of p-bis[2H, 5H-4-oxothiazol-3-yl] phenylenes and p-bis[cis-5H-3,3a-dihydropyrazolo[3,4-d]thiazol-6-yl]phenylenes
The facile synthesis of p-bis[cis-3,3a-dihydro-5H-pyrazolo[3,4-d]thiazol-6- yl]phenylenes 4 has been achieved by the condensation of p-bis[4-substituted phenylimine]phenylenes 1 with thioglycollic acid in toluene, using Dean-Stark water separator, to give
