Nerella A, Jeripothula M. Design, synthesis and biological evaluation of novel deoxyvasicinone-indole as multi-target agents for Alzheimer's disease. Bioorg Med Chem Lett 2021; 49:128212.

Abstract
In this study, a series of multifunctional hybrids (6a-6l) against Alzheimer's disease were designed and obtained by conjugating the pharmacophores of deoxyvasicinone and indole. These analogs of deoxyvasicinone-indole were evaluated as inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), and as inhibitors of amyloid aggregation (Aβ1-42) for treatment of Alzheimer's disease (AD). Subsequently, AChE induced Aβ aggregation inhibition test was also performed for selected compounds. Biological activity results demonstrated that compound 6b was the most potent and balanced dual ChEs inhibitor with IC50 values 0.12 µM and 0.15 µM for eeAChE and eqBuChE, respectively. Kinetic analysis and docking study indicated that compound 6b was a mixed-type inhibitor for both AChE and BuChE. Compound 6b also found to be the best inhibitors of self-induced Aβ1-42 aggregation with IC50 values of 1.21 µM. Compound 6b also afforded excellent inhibition of AChE-induced Aβ1-42 aggregation by 81.1%. Overall, these results indicate that 6b may be considered as lead compound for the development of highly effective anti-AD drugs.

Abstract
Cellulose sulfuric acid has proved its competence as a potential bio-compatible, non-toxic,
and inexpensive heterogeneous solid acid catalyst in synthetic organic chemistry. Owing to its remarkable
properties, such as non-hygroscopic nature, recyclability, superior catalytic activity and high
stability, it has been actively explored as an efficient and biodegradable organocatalyst in diverse
chemical transformations of synthetic relevance. This review attempts to summarize a significant advancement
and catalytic applications of cellulose sulfuric acid for the synthesis of a plethora of biologically
relevant organic molecules.

Abstract
The design of the environmentally friendly approach to the synthesis of biologically important
compounds without compromising the yield has been the focus of many chemists in recent
years. The development of the one-pot synthesis of heterocycles in the presence of Ionic Liquids
(ILs), used as both environmental media and catalysts, is efficient and environmentally sustainable.
This review highlights the one-pot synthesis of imidazoles in acidic ILs in the past decade. Some reviews
have been conducted on imidazoles, such as their pharmacological importance. Hence, we decided
to focus on their synthesis in acidic ionic liquids, which the authors are not aware of any published
literature.

Abstract
A mild, efficient and rapid protocol was developed for the deprotection of alcoholic TBDMS ethers using a recyclable, eco-friendly highly sulphated cellulose sulphate acid catalyst in methanol. This acid catalyst selectively cleaves alcoholic TBDMS ethers in bis-TBDMS ethers containing both alcoholic and phenolic TBDMS ether moieties.
