Curr Comput Aided Drug Des 2018 Dec 6. Epub 2018 Dec 6.

Department of Mechanical Engineering (SMME), National University of Science and Technology, Islamabad . Pakistan.

Background: Huntington's disease is characterized by three side effects, including motor disturbances, psychiatric elements, and intellectual weakness. The onset for HD has nonlinear converse associations with the number of repeat sequences of the polyglutamine mutations, so that younger patients have a tendency for longer repeats length. This HD variation is because of a development of a polyglutamine (CAG) repeats in the exon 1 of the Huntingtin protein. Read More

Molecular Docking Studies of Methamphetamine and Amphetamine-Related Derivatives as an Inhibitor against dopamine Receptor.

Curr Comput Aided Drug Des 2018 Dec 4. Epub 2018 Dec 4.

Department of Medical Biotechnology, School of Medicine, Shahroud University of Medical Sciences, Shahroud. Iran.

Background: The catecholamines such as dopamine, norepinephrine, and epinephrine are neurotransmitters that regulate different physiological functions of the central nervous system. Some evidence suggest that the degeneration of dopamine neurons in the substantia nigra contributes in Parkinson's disease (PD), which is a neurodegenerative disorder and it is responsible for the major symptoms of PD. It is suggested that replenishment of striatal dopamine through the oral administration of the dopamine precursor, levodopa, can compensate the lack of endogenously produced dopamine. Read More

Effects of hydroxyl group on the interaction of carboxylated flavonoid derivatives with S. cerevisiae α-glucosidase.

Curr Comput Aided Drug Des 2018 Oct 22. Epub 2018 Oct 22.

Gansu Province Computing Center, Lanzhou 730000. China.

Carboxyalkyl flavonoids derivatives are considered as effective inhibitors in reducing post-prandial hyperglycaemia. Combined with Density Functional Theory (DFT) and the theory of atoms in molecules (AIM), molecular docking and charge density analysis are carried out to understand the molecular flexibility, charge density distribution and the electrostatic properties of these carboxyalkyl derivatives. Results show that the electron density of the chemical bond C14-O17 on B ring of molecule II increases while O17-H18 decreases at the active site, suggesting existence of weak non-covalent interactions most prominent of which are H-bonding and electrostatic interaction.

Departamento de Informática, Escuela de Ingeniería Informática, University of Valladolid, Segovia, Spain.

Background: Automated compound testing is currently the de facto standard method for drug screening, but it has not brought the great increase in the number of new drugs that was expected. Computer- aided compounds search, known as Virtual Screening, has shown the benefits to this field as a complement or even alternative to the robotic drug discovery. There are different methods and approaches to address this problem and most of them are often included in one of the main screening strategies. Read More

Molecular Docking Analysis of Caspase-3 Activators as Potential Anticancer Agents.

Curr Comput Aided Drug Des 2019 ;15(1):55-66

Use-inspired Biomaterials & Integrated Nano Delivery (U-BiND) Systems Laboratory, Department of Pharmaceutical Sciences, Wayne State University, Detroit, MI, United States.

Introduction: Caspase-3 plays a leading role in apoptosis and on activation, it cleaves many protein substrates in cells and causes cell death. Since many chemotherapeutics are known to induce apoptosis in cancer cells, promotion or activation of apoptosis via targeting apoptosis regulators has been suggested as a promising strategy for anticancer drug discovery. In this paper, we studied the interaction of 1,2,4-Oxadiazoles derivatives with anticancer drug target enzymes (PDB ID 3SRC). Read More

Base Distribution in Dengue Nucleotide Sequences Differs Significantly from Other Mosquito-Borne Human-Infecting Flavivirus Members.

Curr Comput Aided Drug Des 2019 ;15(1):29-44

Department of Physics, Jadavpur University, Jadavpur, Kolkata 700032, India.

Introduction: Among the mosquito-borne human-infecting flavivirus species that include Zika, West Nile, yellow fever, Japanese encephalitis and Dengue viruses, the Zika virus is found to be closest to Dengue virus, sharing the same clade in the Flavivirus phylogenetic tree. We consider these five flaviviruses and on closer examination in our analyses, the nucleotide sequences of the Dengue viral genes (envelope and NS5) and genomes are seen to be quite widely different from the other four flaviviruses. We consider the extent of this distinction and determine the advantage and/or disadvantage such differences may confer upon the Dengue viral pathogenesis. Read More

New Resensitizers for the Nicotinic Acetylcholine Receptor by Ligand-Based Pharmacophore Modeling.

Curr Comput Aided Drug Des 2019 ;15(1):104-109

Bundeswehr Institute of Pharmacology and Toxicology, Neuherbergstrasse 11, 80937 Munich, Germany.

Introduction: Irreversible inhibition of the acetylcholinesterase upon intoxication with organophosphorus compounds leads to an accumulation of acetylcholine in the synaptic cleft and a subsequent desensitization of nicotinic acetylcholine receptors which may ultimately result in respiratory failure. A direct intervention at the nicotinic acetylcholine receptor (nAChR) was proposed as an alternative therapeutic approach to the treatment with atropine and oximes.

Methods: The bispyridinium compound MB327 has been found to recover functional activity of nAChR thus representing a promising starting point for the development of new drugs for the treatment of organophosphate poisoning. Read More

The application of machine learning techniques in the clinical drug therapy.

Curr Comput Aided Drug Des 2018 May 25. Epub 2018 May 25.

Department of Neurology, Xiangya Hospital of Central South University, Changsha. China.

The development of a novel drug is an extremely complicated process that includes the target identification, design and manufacture, and proper therapy of the novel drug, as well as drug dose selection, drug efficacy evaluation, and adverse drug reaction control. Due to the limited resources, high costs, long duration, and low hit-to-lead ratio in the development of pharmacogenetics and computer technology, machine learning techniques have assisted novel drug development and have gradually received more attention by researchers. According to current research, machine learning techniques are widely applied in the process of the discovery of new drugs and novel drug targets, the decision surrounding proper therapy and drug dose, and the prediction of drug efficacy and adverse drug reactions.
