Background and Objectives: The effects of antipsychotic agents, including dopamine D2 receptor blocking agents such as haloperidol, chlorpromazine, and sulpiride, and related compounds such as mirtazapine and sertraline, on dopamine formation from p-tyramine catalyzed by cytochrome P450 (CYP) 2D6.2 (Arg296Cys;Ser486Thr), CYP2D6.10 (Pro34Ser;Ser486Thr), and CYP2D6.39 (Ser486Thr) were compared Read More

Aim: The relationship between CYP1A2 polymorphisms and the steady-state plasma levels of aripiprazole and its active metabolite, dehydroaripiprazole, were investigated in Japanese schizophrenic patients. Background: It has been implied that cytochrome P450 (CYP) 1A2 may play a role in the metabo-lism of aripiprazole. Genetic variations in the CYP1A2 gene have been reported. Objective: The authors investi Read More

Background: Everolimus, an allosteric mechanistic target of rapamycin (mTOR) inhibitor, recently demonstrated the therapeutic value of mTOR inhibitors for Central Nervous System (CNS) indications driven by hyperactivation of mTOR. A newer, potent brain-penetrant analog of everolimus, referred to as (1) in this manuscript [(S)-3-methyl-4-(7-((R)-3-methylmorpholino)-2- (thiazol-4-yl)-3H-imidazo[4,5-b]pyridin-5-yl)morpholin Read More

Background: Bempedoic acid (BEM) belongs to a category of drugs known as Adenosine triphosphate-citrate Lyase (ACL) inhibitors. It is a prodrug with intracellular activation that is administered orally. Bempedoic acid is used to treat existing atherosclerotic cardiovascular diseases, mainly hypercholesterolemia. Methods: For the stability-indicating assay, the HPLC method was employed using a Kromasil 100-5-C8 column (1 Read More

Introduction: MKT-077 and its derivatives are rhodacyanine inhibitors that hold potential in the treatment of cancer, neurodegenerative diseases and malaria. These allosteric drugs act by inhibiting the ATPase action of heat shock proteins of 70 kDa (HSP70). MKT-077 accumulates in the mitochondria and displays differential activity against HSP70 homologs. Methods: The four Plasmodium falciparum HSP70s (PfHSP70) ar Read More

Background: Eltrombopag Olamine is a drug used to treat thrombocytopenia, a disorder where blood platelet counts get lower and severe aplastic anemia. It serves as a thrombopoietin receptor agonist, which give rise to platelet production in the bone marrow. Objectives: The objective of this study is to develop a simple, specific, accurate, precise and economical Ultraviolet spectroscopy method to estimate the amount of Eltr Read More
