Each synthesis of these new drug candidates include multi-steps procedures. Overall, discovering a new drug is a very time-consuming and very costly works. The development of molecular modelling programs and their applications in pharmaceutical research have been formalized as a field of study known computer assisted drug design (CADD) or computer assisted molecular design (CAMD). In this study, using the above techniques, Monoamine Oxidase isozymes, which play an essential role in the oxidative deamination of the biogenic amines, were studied. Compounds that inhibit these isozymes were shown to have therapeutic value in a variety of conditions including several psychiatric and neurological as well as neurodegenerative diseases. First, a series of new pyrazoline derivatives were screened using molecular modelling and docking methods and promising lead compounds were selected, and proposed for synthesis as novel selective MAO-A or –B inhibitors. -

Antipsychotic Drugs Influence Dopamine Neuron Terminals Via Action on D2‐Receptors and Vesicles
Antipsychotic Drugs Influence Dopamine Neuron Terminals via Action on D2‐receptors and Vesicles Alex Klausing Honors Thesis in the Pharmaceutical Sciences Major College of Pharmacy The Ohio State University Advisor: Lane J. Wallace Spring 2013 Abstract Dopamine D2 antagonist antipsychotic drugs share the effects of increasing dopamine synthesis, dopamine neuron firing rate, and dopamine and DOPAC levels. These antagonists all raise extracellular dopamine to approximately 163% of control and DOPAC levels to approximately 200% of control without changing tissue level of dopamine. Variability in striatal tissue DOPAC level (190 – 350% of control) and rates of dopamine synthesis (190‐378% of control) reported after administration of various antipsychotic drugs gives evidence that these parameters are influenced by factors besides the antagonism of the D2 receptor. We used a computational model of dopaminergic terminals in the striatum to determine what parameters other than D2 receptors might be targets for the drugs. Simulation model results suggest that D2 receptor antagonism results in a slight increase in rate of dopamine exocytosis accompanied by a small increase in rate of dopamine synthesis needed to maintain the increase in rate of exocytosis and a small increase in rate of dopamine synthesis specifically dedicated to DOPAC secretion. Simulation model results also suggest that variable increases in levels of tissue DOPAC result from increases in passive diffusion of dopamine out from vesicles coupled with an increase in rate of dopamine synthesis required to maintain tissue levels of dopamine. Biochemical data reported in the literature suggests changes in passive diffusion depend on the ability of the antipsychotic drug to diffuse into and alkalinize vesicles. -

Neuronal Dopamine D3 Receptors: Translational Implications for Preclinical Research and CNS Disorders

Dopamine D3 receptor (D3R) was cloned 30 years ago, and its distribution in the CNS and in the periphery, molecular structure, cellular signaling mechanisms have been largely explored. Involvement of D3Rs has been recognized in several CNS functions such as movement control, cognition, learning, reward, emotional regulation and social behavior. D3Rs have become a promising target of drug research and great efforts have been made to obtain high affinity ligands (selective agonists, partial agonists and antagonists) in order to elucidate D3R functions. There has been a strong drive behind the efforts to find drug-like compounds with high affinity and selectivity and various functionality for D3Rs in the hope that they would have potential treatment options in CNS diseases such as schizophrenia, drug abuse, Parkinson’s disease, depression, and restless leg syndrome. -
Discrimination Between Mechanism-Based Inactivation and Tight Binding Inhibitor Behavior
Biomedical Chemistry: Research and Methods 2020, 3(1), e00115. DOI: 10.18097/bmcrm00115 1 EXPERIMENTAL RESEARCH A SIMPLE APPROACH FOR PILOT ANALYSIS OF TIME-DEPENDENT ENZYME INHIBITION: DISCRIMINATION BETWEEN MECHANISM-BASED INACTIVATION AND TIGHT BINDING INHIBITOR BEHAVIOR O.A. Buneeva, L.N. Aksenova, A.E. Medvedev* Institute of Biomedical Chemistry, 10 Pogodinskaya str., Moscow, 119121 Russia; *e-mail: [email protected] The increase in enzyme inhibition developed during prolonged incubation of an enzyme preparation with a chemical substance may be associated with both the non-covalent and also with covalent enzyme-inhibitor complex formation. The latter case involves catalytic conversion of a mechanism-based irreversible inhibitor (a poor substrate) into a reactive species forming covalent adduct(s) with the enzyme and thus irreversibly inactivating the enzyme molecule. Using a simple approach, based on comparison of enzyme inhibition after preincubation with a potential inhibitor at 4ºC or 37ºC we have analyzed inhibition of monoamine oxidase A (MAO A) by known MAO inhibitors pargyline and pirlindole (pyrazidol). MAO A inhibitory activity of pirlindole (reversible tight binding inhibitor of MAO A) assayed after mitochondrial wash was basically the same for the incubation at both 4ºC and 37ºC. In contrast to pirlindole, the effect of pargyline (mechanism based irreversible MAO inhibitor) strongly depended on the temperature of the incubation medium. At 37ºC the residual activity MAO A in the mitochondrial fraction after washing was significantly lower than in the mitochondrial samples incubated with pargyline at 4ºC. Results of this study suggest that using analysis of both time- and temperature-dependence of inhibition it is possible to discriminate mechanism-based irreversible inhibition and reversible tight binding inhibition of target enzym Key words: enzyme inhibition; time-dependent and temperature-dependent inhibition; mechanism-based inhibitors; reversible tight binding inhibitors DOI: 10.18097/BMCRM00115 INTRODUCTION (England). -
