Abstract
Background:
β-Site amyloidal precursor protein (APP) cleavage enzyme (BACE-1) is
reported as prime cause for progession of Alzheimer’s disease (AD). It is a form of dementia characterized
by degeneration of neurones in brain. Therefore, attempts have been made to find potent
inhibitors of this enzyme.
Methods:
The paper presents an division-based 2D quantitative structure-activity relationship
(QSAR) study on a series of BACE-1 inhibitors to analyse the structural features that may be important
to increase the potency of the compounds.
Results:
The study led to predict some potential leads for the development of potent inhibitors of
BACE-1. One of the molecule with pyrrolidine and pyrrolidinone substitutions exhibited drugreceptor
interactions comparable with reference drug.
Conclusion:
The hydrogen-bond interactions between the molecules and the receptor basically
control the BACE-1 inhibition activity of the compounds.

Abstract
A series of 1-aroyl-3-aryl thioureas derivatives were synthesized and evaluated for antibacterial activity. The results indicated that the compounds possessed higher activity against gram-negative bacteria than gram-positive bacteria. Amongst all these compounds, C18 (89.4%) exhibited the greatest antibacterial activity against gram-negative bacteria while C5 (85.6%) displayed maximum antibacterial activity against gram-positive bacteria. Preliminary study of the structure-activity relationship revealed that an electronic factor on aryl rings had a great effect on the antibacterial activity of these compounds.
