A simple and accurate liquid chromatography coupled with tandem mass spectrometry method was developed for determination and in vivo pharmacokinetic studies of vitexin rhamnoside in rat plasma. Practical utility of this new LC/MS/MS method was confirmed in pilot pharmacokinetic studies in rats following both intravenous and oral administration. Animal studies were carried out in Medicilon.

Liver cancer is the fourth greatest cause of cancer related mortality. AD80 is a multi-kinase inhibitor with anti-tumoral activity across a variety of hepatocellular carcinoma (HCC) preclinical models, including mouse xenografts. AD80 is highly active in a tumor xenograft model. Experimental dosing for AD80 was determined from maximum tolerated dosage (MTD) studies and pharmacokinetic (PK) analysis. Quantities of AD80 in blood plasma were determined by LC-MS/MS at Medicilon.

Targeted protein degradation (TPD) exemplified by PROTACs is an emerging strategy for next generation drug discovery. Threonine tyrosine kinase (TTK) is a dual-specific protein kinase that catalyzes phosphorylation of both serine/threonine and tyrosine residues. Researchers designed and synthesized TTK PROTACs, which demonstrated reasonable pharmacokinetic profiles. All the pharmacokinetic studies were carried out by Medicilon, according to the protocols and guidelines of the institutional care and use committee.

Sulfonylureas exert their anti-diabetic effects by inhibiting K-ATP channels in the plasma membrane of islet β-cells. Chlorpropamide acts on complex II directly or indirectly via mitoK-ATP to produce mtROS as a pro-longevity signal. Chlorpropamide has an anti-aging effect on worms and human lung fibroblast MRC-5 cells. Determination of Chlorpropamide bioavailability in mice was performed by Medicilon.

Uncovering new therapeutics for kidney fibrosis hold promise for chronic kidney disease (CKD). BRD4 inhibition ameliorated kidney injury and fibrosis. ZLD2218 exhibited the potent inhibitory activity against BRD4, with the IC50 value of 107?nM. Pharmacokinetic analysis of of ZLD2218 were analyzed by noncompartmental methods using Phoenix WinNonlin 7.0 (Accomplished by Medicilon).

Immune checkpoint blockade therapies have changed the paradigm of cancer therapies. Reseachers performed in vivo screening for anti-PD-1 therapy across 23 syngeneic tumor models and found that CT-26 and Colon 26, which are murine colorectal carcinoma derived from BALB/c mice, showed different sensitivity to anti-PD-1. In vivo studies for anti-PD-1 antibody across 23 syngeneic tumor models were performed by Medicilon.

Phosphodiesterase-1 (PDE1) is a promising drug target closely related to central and peripheral diseases. Compound 2j with the IC50 of 21 nM against PDE1B, shows good metabolic stability in the rat liver microsomes. Stability test in the rat liver microsomes were performed by Medicilon.

Idiopathic pulmonary fibrosis is a chronic and lethal lung disease associated with fibroblast activation, myoblast proliferation and extracellular matrix deposition. SKLB-YTH-60 was developed through computer-aided drug design, de novo synthesis and high-throughput screening. YTH-60 has obvious anti‐proliferative activity on fibroblasts and A549 cells. YTH-60 has an acceptable oral bioavailability and appropriate eliminated half-life time. The in vivo pharmacokinetic study of YTH‐60 was performed by Medicilon.

PROTAC is an attractive technology in drug discovery. Researchers successfully discovered an orally available PROTAC degrader SIAIS164018 which degrades not only ALK or mutant EGFR but also oncoproteins involved in metastasis. SIAIS164018 is orally bioavailable and well tolerated in vivo. Pharmacokinetic and maximal tolerated dose (MTD) assays were performed by Medicilon.

TOP5300 is an orally active follicle stimulating hormone receptor allosteric agonist that provides a preferred treatment for over 16 million infertile women of reproductive age in low complexity methods or in high complexity methods. TOP5300 was evaluated in standard ADME, including Cytochrome P450 inhibition, clearance and pharmacokinetic profiles. Toxicological evaluations were performed in both rat and dog as the second species according to the guidance from FDA. These assays were performed by Medicilon.
