6'7'-Epoxybergamottin is a furanocoumarin found in grapefruit. It is a potent inhibitor of the cytochrome P450 (CYP) isoform CYP3A4 with an IC50 value of 0.30 ppm in a cell-free assay, 0.33 μM in HL7 human liver cells, and 0.22 μM in S9 human intestine cells. It has been studied in the context of druginteractions with grapefruit constituents. It is found in grapefruit juice at concentrations of 0.1-7.4 μM and inhibits the transport of talinolol , a permeability glycoprotein (P-gp/ABCB1) transporter substrate, across Caco-2 cell monolayers (IC50 = 0.7 μM). 6'7'-Epoxybergamottin also has insecticidal properties with a concentration of 5 μg/cm2 leading to 100% mortality of adult olive fruit flies.
Ga(III)protoporphyrin-IX, a model for interporphyrin interactions in malaria pigment, possesses potent antibacterial effects against gram-negative, gram-positive, and acid-fast bacteria. It exhibits high solubility in methanol (MeOH) and serves as a malarial pigment analogue for drug development, as well as a potential antibacterial agent.
5-HT7 receptor ligand 1 (Compound 5c) is a potent ligand for the 5-HT7 receptor, with a K i value of 8 nM. The compound demonstrates non-hepatotoxic properties and displays moderate potential for drug-druginteractions with substrates of CYP3A4 or CYP2D6 enzymes [1].
ARRY-403, also known as AMG-151, is an orally available allosteric glucokinase (GK) activator developed for the treatment of type 2 diabetes mellitus (T2DM). ARRY-403 has many favorable physicochemical characteristics and ADME properties (low potential to cause drug–druginteractions (DDIs). ARRY-403 potently activates human glucokinase (GK) in vitro (EC50 = 79 nM at 5 mM glucose), with an S0.5 = 0.93 mM glucose (ARRY-403 at 5 mM) and Vmax = 134% compared to the no activator control. It possesses good in vitro drug-like properties (aqueous solubility, cell permeability, low low potential for drug-druginteractions, low predicted hepatic clearance), and selectivity against broad panels of receptors and enzymes.
