DESIGNING OF COUMARIN DERIVATIVES AS SQUALENE SYNTHASE INHIBITORS

Biphenylquinuclidines as inhibitors of squalene synthase and growth of parasitic protozoa.

In this paper we describe the preparation of some biphenylquinuclidine derivatives and their evaluation as inhibitors of squalene synthase in order to explore their potential in the treatment of the parasitic diseases leishmaniasis and Chagas disease. The compounds were screened against recombinant Leishmania major squalene synthase and against Leishmania mexicana promastigotes, Leishmania dono...

Synthesis novel bis-Coumarin derivatives as potential acetylcholinestrase inhibitors: An in vitro, molecular docking, and molecular dynamics simulations study

Alzheimer's disease is an irreversible and progressive brain disorder that slowly destroys memory and thinking skills and ultimately the ability to do the simplest things and can lead to death. Cholinesterases (ChEs) play an important role in controlling cholinergic transmission, and subsequently, by inhibiting CHEs, acetylcholine levels in the brain are elevated. Coumarins have been shown to e...

Identification of coumarin derivatives as a novel class of allosteric MEK1 inhibitors.

A homogenous TR-FRET-based in vitro coupling assay for the MAP3Ks-MEK1-ERK2 kinase cascade was established and was used to screen for inhibitors of the ERK/MAPK pathway. A series of coumarin derivatives were identified from the screen. These compounds potently inhibit the activation of the unactivated human MEK1 by upstream MAP3Ks (including BRAF and COT), but do not inhibit the activity of the...

Design and Microwave Assisted Synthesis of Coumarin Derivatives as PDE Inhibitors.

Coumarins appended to benzimidazole through pyrazole are designed and synthesized using microwave irradiation. These compounds were analyzed for phosphodiesterase (PDE) inhibition indirectly by motility pattern in human spermatozoa. Some of the synthesized compounds, namely, 5d, 5e, 5f, 5g, 5h, and 5k, have exhibited potent inhibitory activity on PDE.
