In Silico Methods for Drug Repositioning and Drug-Drug Interaction Prediction
In silico Methods for Drug Repositioning and Drug-Drug Interaction Prediction Pathima Nusrath Hameed ORCID: 0000-0002-8118-9823 Submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy Department of Mechanical Engineering THE UNIVERSITY OF MELBOURNE May 2018 Copyright © 2018 Pathima Nusrath Hameed All rights reserved.

Abstract Drug repositioning and drug-drug interaction (DDI) prediction are two fundamental ap- plications having a large impact on drug development and clinical care. Drug reposi- tioning aims to identify new uses for existing drugs. Moreover, understanding harmful DDIs is essential to enhance the effects of clinical care. Exploring both therapeutic uses and adverse effects of drugs or a pair of drugs have significant benefits in pharmacology. The use of computational methods to support drug repositioning and DDI prediction en- able improvements in the speed of drug development compared to in vivo and in vitro methods. This thesis investigates the consequences of employing a representative training sam- ple in achieving better performance for DDI classification. The Positive-Unlabeled Learn- ing method introduced in this thesis aims to employ representative positives as well as reliable negatives to train the binary classifier for inferring potential DDIs. Moreover, it explores the importance of a finer-grained similarity metric to represent the pairwise drug similarities. Drug repositioning can be approached by new indication detection. In this study, Anatomical Therapeutic Chemical (ATC) classification is used as the primary source to determine the indications/therapeutic uses of drugs for drug repositioning. -

There are several LC-MS/MS; WADA; major categories of this drug class and the compounds vary greatly in Drugs of abuse. structure, physicochemical properties, effects on urinary composition and renal haemodynamics, and site mechanism of action. Diuretics are often abused by athletes to excrete water for rapid weight loss and to mask the presence of other banned substances. Because of their abuse by athletes, ’s (WADA) diuretics have been included in the World Anti-Doping Agency list of prohibited substances. The diuretics are routinely screened by anti- doping laboratories as the use of diuretics is banned both in-competition and out-of-competition. This work provides an improved, fast and selective –tandem mass spectrometric (LC/MS/MS) method liquid chromatography for the screening of 22 diuretics and probenecid in human urine. The samples preparation was performed by liquid-liquid extraction. The limit of detection (LOD) for all substances was between 10-20 ng/ml or better. -
New Prohibited Substances Addition to Procedures Using Triple Quadrupole LC/MS2 Technique
Poster MANFRED DONIKE WORKSHOP Pop V, Bican G, Pop A, Lamor M, Zorio M New prohibited substances addition to procedures using triple quadrupole LC/MS2 technique Romanian Doping Control Laboratory, Bucharest, ROMANIA Abstract New substances are added each year to the different classes of substances of WADA’s Prohibited List and have to be included in the test menu of each accredited doping control laboratory. For the analysis of some of these compounds the technique of choice is the LC/MS2 technique. Furthermore, with the decrease of MRPL levels, for stimulants from 500 ng/mL to 100 ng/mL and for narcotics from 200 ng/mL to 50 ng/mL, beginning from the entering in force on 1 January 2013 of the new WADA Technical Document TD2013MRPL, some of the compounds analyzed by the current GC/MS based procedure for stimulants and narcotics needed to be transferred to the LC/MS2 based procedure in order to lower their limit of detection. This paper-work presents the optimal conditions for preparation, separation and identification of new substances introduced to the LC/MS2 technique based procedures during the year 2012. Introduction Liquid chromatography coupled with mass spectrometry is increasingly used in doping control laboratories [1]. The current work presents the optimization of the LC/MS2 detection parameters and the introduction of the prohibited substances in the existent procedures, depending on the characteristics of the studied compounds. The studied compounds are benzthiazide, cyclopenthiazide, cyclothiazide, epitizide, hydroflumethiazide and polythiazide (thiazide diuretic compounds), tramadol and its O-desmethyl metabolite (narcotic compound from the monitoring program [2]), cyclazodone, pentetrazole, prolintane, propylhexedrine and selegiline (stimulants transferred from the GC/MS- to the LC/MS2-based procedure due to the decreasing of the MRPL levels for stimulants and narcotics [3]). -

DIURETICS Diuretics Are Drugs That Promote the Output of Urine Excreted by the Kidneys
DIURETICS Diuretics are drugs that promote the output of urine excreted by the Kidneys. The primary action of most diuretics is the direct inhibition of Na+ transport at one or more of the four major anatomical sites along the nephron, where Na+ reabsorption takes place. The increased excretion of water and electrolytes by the kidneys is dependent on three different processes viz., glomerular filtration, tubular reabsorption (active and passive) and tubular secretion. Diuretics are very effective in the treatment of Cardiac oedema, specifically the one related with congestive heart failure. They are employed extensively in various types of disorders, for example, nephritic syndrome, diabetes insipidus, nutritional oedema, cirrhosis of the liver, hypertension, oedema of pregnancy and also to lower intraocular and cerebrospinal fluid pressure. Therapeutic Uses of Diuretics i) Congestive Heart Failure: The choice of the diuretic would depend on the severity of the disorder. In an emergency like acute pulmonary oedema, intravenous Furosemide or Sodium ethacrynate may be given. In less severe cases. Hydrochlorothiazide or Chlorthalidone may be used. Potassium-sparing diuretics like Spironolactone or Triamterene may be added to thiazide therapy. ii) Essential hypertension: The thiazides usually sever as primary antihypertensive agents. They may be used as sole agents in patients with mild hypertension or combined with other antihypertensives in more severe cases. iii) Hepatic cirrhosis: Potassium-sparing diuretics like Spironolactone may be employed. If Spironolactone alone fails, then a thiazide diuretic can be added cautiously. Furosemide or Ethacrymnic acid may have to be used if the oedema is regractory, together with spironolactone to lessen potassium loss. Serum potassium levels should be monitored periodically. -
