Alzheimer’s disease (AD) is a slowly progressive neurodegenerative disease that causes dementia in people aged 65 and over. In the present study, a series of thiadiazole hybrid compounds with benzothiazine derivatives I (R = Et, Pr, t-Bu, etc.) as acetylcholinesterase inhibitors were developed and evaluated for their biol. activity. The AChE and BChE inhibition potentials of all compounds were evaluated by using the in vitro Ellman method. The biol. evaluation showed that compounds I (R = 4-OMeC6H4) and I (R = 4-ClC6H4) displayed significant inhibitory activity against AChE and showed IC50 values of 0.027μM and 0.025μM against AChE, resp. The reference drug donepezil (IC50 = 0.021μM) also showed significant inhibition against AChE. Further docking simulation also revealed that the above compounds interacted with the active site of the enzyme similarly to donepezil. The antioxidant study revealed that the above two compounds exhibited greater antioxidant effects. An in vitro blood-brain barrier permeability study showed that compounds I (R = 4-OMeC6H4) and I (R = 4-ClC6H4) are promising compounds against AD. The cytotoxicity study of the above compounds showed non-cytotoxic with an IC50 value of 98.29 ± 3.98μM and 159.68 ± 5.53μM against NIH/3T3 cells, resp. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Quality Control of Isopropylisothiocyanate).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Quality Control of Isopropylisothiocyanate
