On the basis of computer prediction of biological activity by PASS and toxicity by DEREK, the most promising 32-alkylaminoacyl derivatives of 3-aminobenzo[d]isothiazole were selected for possible local anaesthetic action. This action was evaluated using an in vitro preparation of the isolated sciatic nerve of the rat and compared with lidocaine which was used as a reference compound. QSAR studi...
A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe-Ziegler cyclization. In addition to an adenosine and a guanosine mimic, analogues of the noncanonical xanthosine, isoguanosine, and 2-aminoadenosine were also synthesized and found to be emissive. Isothiazolo 2-aminoadenosine, an...
A DFT Study on Single Brønsted Acid Sites in Zeolite Beta and Their Interaction with Probe Molecules
Zeolites are subjects of intensive research, as they have vast industrial applications. However, exact nature catalytic active sites remains elusive. With this we attempt to shed light on the Brønsted acid in zeolite beta modification A and correlate widely used TPD methods their identification with theoretically determined strongest weakest sites. diverse set probe molecules a wide range stren...
