Stability behaviour of antiretroviral drugs and their combinations. 11: Characterization of interaction products of zidovudine and efavirenz, and evaluation of their anti HIV-1 activity, and physiochemical and ADMET properties
Zidovudine (ZDV) and efavirenz (EFV), which belong to two separate classes of antiretroviral drugs, viz., NRTI and NNRTI, respectively, were subjected to different stability test conditions alone and in solid mixtures to evaluate possibility of interaction among them.
Feature of the week #65: Time-to-event modeling with Monolix
Monolix uses a parametric approach to model time-to-event data, via the definition of a hazard function.
Brain Targeting of Acyl-CoA:Cholesterol O-Acyltransferase-1 Inhibitor K-604 via the Intranasal Route Using a Hydroxycarboxylic Acid Solution
An acyl-CoA:cholesterol O-acyltransferase-1 (ACAT-1/SOAT-1) inhibitor, K-604 is a promising drug candidate for the treatment of Alzheimer’s disease and glioblastoma; however, it exhibits poor solubility in neutral water and low permeability across the blood–brain barrier.

Development of liquid chromatography tandem mass spectrometry method to quantify cyclobutane pyrimidine dimer photolyase activity by detection of 15mer oligonucleotide as reaction product
Ultraviolet radiation from sunlight causes DNA damage in skin cells by formation of photoproducts, mainly cyclobutane pyrimidine dimers (CPD), which are reverted by exogenous CPD-photolyase, preventing photoaging and skin cancer.
A New Method for Classification of Salts and Cocrystals Using Solid-State UV Spectrophotometry
Salt and cocrystal formulations are widely used as techniques to improve physicochemical properties of compounds.
A novel five‐step synthetic route to 1,3,4‐oxadiazole derivatives with potent α‐glucosidase inhibitory potential and their in silico studies
A series of new N‐aryl/aralkyl derivatives of 2‐methyl‐2‐{5‐(4‐chlorophenyl)‐1,3,4‐oxadiazole‐2ylthiol}acetamide were synthesized by successive conversions of ...

Changes in murine respiratory dynamics induced by aerosolized carfentanil inhalation: efficacy of naloxone and naltrexone
Carfentanil (CRF) is an extremely potent opioid capable of inducing fatal respiratory depression.
Utilizing the Combination of Binding Kinetics and Micro-Pharmacokinetics Link in Vitro α-Glucosidase Inhibition to in Vivo Target Occupancy
Many compounds with good inhibitory activity (i.e., high affinity) within in vitro experiments failed in vivo studies due to a lack of efficacy from limited target occupancy (TO) in the drug discovery process.
The Physicochemical and Pharmacokinetic Properties of Benzodiazepines Appearing as New Psychoactive Substances
Benzodiazepines are a class of compounds that were initially developed for medicinal purposes.
Biopredictive in vitro testing methods to assess intestinal drug absorption from supersaturating dosage forms
The discovery pipelines in pharmaceutical companies are highly populated with poorly soluble compounds, demanding for an appropriate solution to overcome this problem.
Food ingredient safety evaluation: Utility and relevance of toxicokinetic methods
The use of toxicokinetic (TK) data is becoming more prevalent in the evaluation of food ingredient safety as more TK information is being incorporated in safety data packages.

Prediction of pharmacokinetic drug-drug interactions causing atorvastatin-induced rhabdomyolysis using physiologically based pharmacokinetic modelling
Atorvastatin and its lactone form metabolite are reported to be associated with statin-induced myopathy (SIM) such as myalgia and life-threatening rhabdomyolysis.
The solubility-absorption trade-off in using solubilizers: mechanistic PK simulations of progesterone with explicit cyclodextrin
Cyclodextrins improve solubility of poorly soluble lipophilic drugs due to 1:1 complexation in their nonpolar interior cavity.
Design, synthesis, and biological activity of Plastoquinone analogs as a new class of anticancer agents
In this paper, based on Plastoquinone (PQ) analogs possessing substituted aniline containing alkoxy group(s), new 2,3-dimethyl-5-amino-1,4-benzoquinones (PQ1-15) were designed and synthesized in either two steps or one-pot reaction.
