Alzheimer’s disease (AD) is a multifactorial neurological disease that mainly affects the old age people. Neuropathologically, AD is characterized by low level of acetylcholine, loss of synapses and neurons in certain brain regions, accumulation of extracellular amyloid beta peptide (Aβ) and phosphorylation of intracellular tau protein. Patients with AD are characterized by various symptoms such as memory deficits, depression, cognitive dysfunction and difficult to perform daily activities. Currently available drugs for the treatment of AD are used to treat symptomatic relief at an early stage

Abstract Heterocyclic compounds are an important class of organic compound. Owing to their usefulness in synthetic processes, numerous heterocyclic compounds are currently known, and this number is growing quickly. The uses of heterocyclic compounds are numerous. They are mostly used as veterinary goods, agricultural chemicals, and medications. Additionally, they are used as sanitizers, cleansers, antioxidants, corrosion inhibitors, co-polymers, and dye ingredients.

Abstract:
The aim of the study is the synthesis and testing for pesticidal activities of 2,3-dimethoxy-16,16-dimethyl-D-homo-8-azagona-1,3,5 (10),13-tetraene-12,17а-one and 2,3-dimethoxy-16,16-dimethyl-d-homo-8-azagona-1,3,5(10),13-tetraene-12-imino-17а-one hydrochloride which could become the basis of plant protection products. The first compound was obtained by condensation of 6,7-dimethoxy-2,3-dihydroisoquinoline with 2-acetyl-5.5-dimethylcyclohexane-1,3-dione. The second substance was synthesized by interaction of the first with ammonium chloride. The synthesized compounds were tested for certain ty
