Cell division cycle 7 (CDC7), a serine/threonine kinase, plays important roles in the initiation of DNA replication. TAK-931, a highly specific CDC7 inhibitor, acts as a next-generation of replication stress (RS) inducer. Combination treatment with TAK-931 and immune checkpoint inhibitors (ICIs) enhances antiproliferative activities in preclinical syngeneic mouse models. The flowcytometry (FCM)-based immune profiling panel studies in J558 allograft syngeneic mouse models were performed at Medicilon. In vivo efficacy studies in J558 allograft models in combination with anti-mPD-1, anti-mPD-L1, and anti-mCTLA-4 antibodies were performed at Medicilon. Therapeutic potential of TAK-931 in antitumor efficacy and immunity, which may improve clinical benefit of the currently-used immunotherapy by combination treatment.

Chrysin is a natural flavonoid that has been reported as a potential treatment for non-alcoholic fatty liver disease (NAFLD). Researchers synthesized a novel chrysin derivative prodrug (C-1) and further investigated its potential therapeutic mechanism against NAFLD in vitro and in vivo. C-1 had a low toxicity profile. Their data demonstrated that C-1 may be a promising agent for NAFLD therapy. Evaluation experiments of the acute toxicities of C-1 were conducted by Medicilon.

Replication stress (RS) is a cancer hallmark; chemotherapeutic drugs targeting RS are widely used as treatments for various cancers. To develop next-generation RS-inducing anticancer drugs, cell division cycle 7 (CDC7) has attracted attention as a target. Researchers have developed an oral CDC7-selective inhibitor, TAK-931, as a candidate clinical anticancer drug. TAK-931 demonstrated marked, dose-dependent antitumor activity, without severe body weight loss. Antitumor efficacy studies for TAK-931 were carried out in two pancreatic PDX models, PHTX-249Pa and PHTXM-97Pa, at Medicilon.

​Alzheimer's disease (AD) is the most universal age-related neurodegenerative disease. AP39 is a newly synthesized mitochondrially targeted H2S donor on mitochondrial function. AP39 increases intracellular H2S levels, mainly in mitochondrial regions. AP39 exerts dose-dependent effects on mitochondrial activity in APP/PS1 neurons. AP39, a novel mitochondria-targeted H2S donor, was designed and synthesized by Medicilon.

Alzheimer's disease (AD) is a progressive and devastating neurodegenerative disorder, characterized by the presence of β-amyloid (Aβ) peptide plaques, neurofibrillary tangles, and neuroinflammation. Receptor for advanced glycation end products (RAGE) belongs to the immunoglobulin superfamily, which functions as a cell surface acceptor for Aβ peptide. RAGE plays an important role in the Aβ-mediated neuronal damage that closely related to the pathogenesis of AD. In this study, Compound 12 showed good dual-target bioactivities against RAGE and SERT in vitro, good liver microsomal stability, and acceptable pharmacokinetic properties. Pharmacokinetic studies were commissioned by Medicilon.

TRIM24 (tripartite motif-containing protein 24) and BRPF1 (bromodomain and PHD finger containing protein 1) are epigenetics “readers”and potential therapeutic targets for cancer and other diseases. Y08624 (Compound 20l) is a new TRIM24/BRPF1 dual inhibitor. Y08624 displays reasonable Caco-2 permeability. Caco-2 permeability assay was performed by Medicilon.

Apoptosis is a cellular process critical to the normal development and homeostasis of multicellular organisms. The inhibitor of apoptosis proteins (IAPs) are a class of key apoptosis regulators. IAP proteins are attractive cancer therapeutic targets. SM-406 (compound 2) is a potent and orally bioavailable antagonist of the IAPs. Pharmacokinetic (PK) studies of SM-406 (compound 2) in male Sprague Dawley rats, beagle dogs and cynomolgus monkeys (non-human primates) were performed by the Division of Pharmacokinetics and Metabolism, Medicilon. SM-406 (compound 2) has an excellent PK profile and good oral bioavailability in each of these four species.

Gastric cancer is the second most lethal cancer across the world. Compounds 8f, inhibits FGFR1 signaling pathways as well as induces cell apoptosis, is a potential agent for the treatment of gastric cancer. The pharmacokinetical profile (PK) of 8f was tested in SD rats. Compound 8f showed an acceptable half-time of 3 h and displayed moderate maximum concentrations, which is enough to meet the concentration of the compound 8f to exert its efficacy in vivo. The pharmacokinetic analysis was performed by the testing service provided by Medicilon.

Epigenetic modification, like DNA methylation, plays a major role in the expression of genetic information. The DNA methyltransferases (DNMTs), maintain DNA methylation, is an attractive target for tumor chemotherapy. WK-23 displays a good inhibitory effect on human DNMT1 with an IC50 value of 5.0 µM. The PK profile of WK-23 was obtained with quite satisfying oral bioavailability and elimination half-life. In vivo pharmacokinetic properties of WK-22, WK-23, WK-27, and DC_517 were performed by Medicilon.

Fructose-1,6-bisphosphatase (FBPase) is a promising target associated with cancer and type 2 diabetes. Compounds W8 and W8k exhibit high selectivity against FBPase and W8 effectively reduces blood glucose in an Institute of Cancer Research (ICR) mice model and dose-dependent inhibition of glucose production in a primary mouse hepatocyte model. The pharmacokinetic studies of W8 and its leaving group saccharin were performed by Medicilon.
