: In the drug discovery setting, undesirable ADMET properties of a pharmacophore with good predictive power obtained after a tedious drug discovery and development process may lead to late-stage attrition. The early-stage ADMET profiling has introduced a new dimension to leading development. Although several high-throughput in vitro models are available for ADMET profiling, however, the in silico methods are gaining more importance because of their economic and faster prediction ability without the requirements of tedious and expensive laboratory resources. Nonetheless, in silico ADMET tools alone are not accurate and, therefore, ideally adopted along with in vitro and or in vivo methods in order to enhance predictability power. This review summarizes the significance and challenges associated with the application of in silico tools as well as the possible scope of in vitro models for integration to improve the ADMET predictability power of these tools.

RÉSUMÉ: La D-sérine en neurobiologie : neurotransmission et neuromodulation dans le SNC. l'homochiralité est fondamentale à la vie. Chez les organismes vivants, seuls les acides aminés lévogyres sont utilisés comme substrats pour la polymérisation et la formation de peptides et de protéines. Cependant, des acides aminés dextrogyres ont été détectés récemment dans différents organismes vivants dont des mammifères. parmi ces acides daminés, la d-sérine a été la plus étudiés. la d-sérine jouerait un rôle important comme neurotransmetteur dans le système nerveux central (SnC) chez l'humain en se liant au récepteur de la n-méthyl-d-aspartate (nMdar). la d-sérine se lie avec une haute affinité à un site co-agoniste du nMdar et, avec le glutamate, sert de médiateur dans plusieurs processus physiologiques et pathologiques vitaux dont la transmission nMdar, la plasticité synaptique et la neurotoxicité. C'est pourquoi on pense que la d-sérine jouerait un rôle clé comme déterminant de la neurotransmission médiée par nMdar dans le SnC des mammifères. dans ce contexte, nous revoyons les fonctions connues de la d-sérine en physiologie humaine, telles le développement du SnC et certaines pathologies comme les maladies neuropsychiatriques et neurodégénératives en lien avec une dysfonction de nMdar.

Acetonitrile and acetone were much more effective than methanol and ethanol at reducing the levels of proteins in plasma. The ability of different solvents to decrease levels of phospholipids in plasma samples was assessed using electrospray ionisation mass spectrometry (MS). Phospholipid signals can obscure differences between samples in general metabolite profiling (i.e. non-target compound) studies. Acetonitrile was much more effective than methanol in reducing the MS signal due to phospholipids in plasma which is a consequence of the poor solubility of phospholipids in acetonitrile. The capability of the solvents at reducing salts in urine samples was also studied by using an amperometric method. Using this approach little difference was detected between methanol, ethanol, acetonitrile and acetone in their ability to desalt urine samples.
