The vertical electronic spectrum of oxoglaucine by means of a multireference configuration interaction method (DFT/MRCI) was studied. The effect of both methyl and methoxy groups on the geometries and energetic distribution of the low-lying excited s

La lipasa B de Candida antarctica (CalB) se ha utilizado en la acilación quimio- y enantioselectiva del racemato (R,S)-propranolol. CalB tiene enantioselectividad moderada (E=63) por el R-propranolol. La enantioselectividad, se origina en la reacci

Racemic mixtures of twelve common a-amino acids and three chiral drugs were tested for the separation of their enantiomers by ion mobility spectrometry (IMS)-quadrupole mass spectrometry (MS). Separations were tested by introducing chiral selectors i

We studied the bis-allylic proton transferreaction from 1,4-pentadiene to superoxideradical anion (O2·־). Minima andtransition state geometries, as well asthermochemical parameters were computedat the B3LYP/6-311+G(3df,2p)level of theory. The elect

In some dermal diseases with evident skin dehydration and desquamation, the natural ratio of CER[NP]:CER[AP] is altered in the extracellular matrix of the stratum corneum by increasing the concentration of CER[AP]. The extracellular matrix of the str

The selective N-acylation of 1,2-amino alcohols has been proposed to occur through the proton shuttle mechanism. However, the O-acetylation of propranolol catalyzed by Candida antarctica lipase B is an exception. We investigated the relation between

We employed a computational modeling approach to study the Michaelis complexes of (R)- and (S)-propranolol with serine-acylated Candida antarctica lipase B using four acyl groups: ethanoyl, butanoyl, octanoyl and hexadecanoyl. Our methodology involve
