Cholinesterase namely, acetyl- and butyrylcholinesterase (AChE and BChE, respectively), has been recognized as a primary class of enzyme that hydrolyzes the acetylcholine (ACh) neurotransmitter in synaptic junctions. Diminished levels of the neurotransmitter in synaptic junction lead to Alzheimerís disease (AD). Inhibition of cholinesterase is thus, an attractive strategy for AD treatment. The study includes the synthesis and characterization of a series of 2-, 3- and 4-aminobenzoic acid derivatives (1a?5c), their biological screening against cholinesterase enzyme and molecular docking study to demonstrate putative binding modes. Antioxidant potential of the synthesized series was also determined. The cholinesterase enzyme inhibition assay showed that compound 5b has the highest inhibition potential against acetylcholinesterase with an IC50 value of 1.66 ± 0.03 μM while in case of butyrylcholinesterase, compound 2c has the highest inhibitory potential with an IC50 value of 2.67 ± 0.05 μM. Molecular docking studies supports the results of enzyme inhibition potential with binding energy value ?G = -9.54 Kcal mol-1 for compound 5b in case for acetylcholinesterase while for butyrylcholinesterase, ?G = -5.53 Kcal mol-1 was obtained for compound 2c. The synthesized series of compounds also shows mild to moderate antioxidant potential. The benzoyl- containing compounds shows better antioxidant activity as compared to other derivatives of the synthesized series. Based on the molecular docking studies and enzyme inhibition potential, the synthesized series of compounds can be regarded as potent cholinesterase inhibitors and can be used for designing and synthesizing more potent drugs for Alzheimerís disease and neurodegenerative diseases.

Schistosomiasis is a major neglected parasitic disease that affects more than 265 million people worldwide and for which the control strategy consists of mass treatment with the only available drug, praziquantel. In this study, a series of new benzohydroxamates were prepared as potent inhibitors of Schistosoma mansoni histone deacetylase 8 (smHDAC8). Crystallographic analysis provided insights into the inhibition mode of smHDAC8 activity by these 3-amidobenzohydroxamates. The newly designed inhibitors were evaluated in screens for enzyme inhibitory activity against schistosome and human HDACs. Twenty-seven compounds were found to be active in the nanomolar range, and some of them showed selectivity toward smHDAC8 over the major human HDACs (1 and 6). The active benzohydroxamates were additionally screened for lethality against the schistosome larval stage using a fluorescence-based assay. Four of these showed significant dose-dependent killing of the schistosome larvae and markedly impaired egg laying of adult worm pairs maintained in culture.

Monoamine oxidase-B (MAO-B) inhibitor has been used as neuroprotectants to treat the motor deficits of Parkinson's disease (PD). We designed and synthesized a class of 8-substituted benzamido-phenylxanthine derivatives as MAO-B inhibitors. The compounds have various inhibitory effects, with compound 6a having a Ki value of 0.26 lM. Their promising activity in vitro suggests potential use in the treatment of PD.
