Excited-State Parameters of One Intramolecular Cyclization by TD-DFT, CIS and ZINDO Methods
Using a time-dependent-density functional theory (TD-DFT), Configuration Interaction Singles (CIS) and Zerner’s Intermediate Neglect of Differential Overlap (ZINDO) methods, we have investigated the UV-Visible spectra of one new intramolecular cyclization at before and after intramolecular attack. All structures were optimized at the B3LYP/6-311++G** level while UV-Visible parameters were calcul...
متن کاملThermal-Dependent dehydration process and intramolecular cyclization of lisinopril dihydrate in the solid state.
The pathway of dehydration and intramolecular cyclization of lisinopril dihydrate in the solid state was investigated using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and a combination of thermal analyzer with Fourier transform infrared microspectroscopy (thermal FT-IR microscopic system). The results indicate that the dehydration from the solid-state lisinopril d...

متن کاملComplexation of acetyl-D-alanyl-D-alanine by antibiotic A35512B.
Antibiotic A3 5512B1.2) is a member of the glycopeptide family of antibiotics; complete structures have been reported for two members of this group, vancomycin3' and ristocetin A4' a) . Both vancomycin and ristocetin have been shown to form complexes with mucopeptides containing the terminal dipeptide D-alanyl-D-alaninee) ; this interaction within the bacterial cell inhibits crosslinking of the...
متن کاملIntestinal absorption of stereoisomers of dipeptides in the rat.
1. Studies have been made of jejunal absorption rates in vivo in the rat of the stereoisomers of alanylphenylalanine, leucyl-leucine and glycyltryptophan. Absorption rates of L-alanyl-L-phenylalanine were about 200 times those of D-alanyl-D-phenylalanine, L-leucyl-L-leucine about 24 times those of the DD-isomer, and glycyl-L-tryptophan 5 times those of glycyl-D-tryptophan. The mixed DLand LD-is...
