表观遗传修饰，如DNA甲基化，在遗传信息的表达中发挥着重要作用。DNA甲基转移酶维持DNA甲基化，是肿瘤化疗的一个有吸引力的靶点
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.

药物发现中的挑战之一是识别高质量的先导化合物。此研究中PK结果表明L12可作为针对PDE5的先导化合物，进一步研究和开发。L12的PK分析通过美迪西进行
Scaffold hopping refers to computer-aided screening for active compounds with different structures against the same receptor to enrich privileged scaffolds, which is a topic of high interest in organic and medicinal chemistry. One of the biggest challenges in drug discovery is to identify high-quality hit and lead compounds. Lead L12 had an IC50 of 8.7 nM and exhibited a different binding pattern in its crystal structure with PDE5 from the famous starting drug tadalafil, and PK results indicate that L12 could be used as a promising lead for further development. Pharmacokinetic properties of L12 were analyzed by Medicilon.

ANO1是一个潜在的镇痛靶点。DFBTA是一种有效的ANO1抑制剂，具有优异的药代动力学特性。体内PK测试通过美迪西进行
Current pain management is largely limited to opioids and non-steroidal anti-inflammatory drugs. Developing new analgesic drugs remains important to address the unmet medical needs of chronic pain patients. Calcium-activated chloride channel anoctamin-1 (ANO1) is a potential analgesic target. DFBTA is a potent inhibitor with the IC50 of 24 nM. DFBTA shows very weak cytotoxicity, cardiotoxicity, and acute toxicity, as well as excellent pharmacokinetics properties with oral bioavailability >75% and little brain penetration (<1.5% brain/plasma). In vivo PK were tested by Medicilon.

XY153是一种有潜力的先导化合物，可用于开发针对急性髓系白血病。XY153在体外具有良好的代谢稳定性。所有肝微粒体测定均通过美迪西进行
Pan-bromodomain and extra terminal (Pan-BET) inhibitors show profound efficacy but exhibit pharmacology-driven toxicities in clinical trials. The representative Compound 8l (XY153), a novel BD2-selective BET inhibitor, potently binds to BRD4 BD2 with an IC50 value of 0.79 nM. XY153 displayed potent antiproliferative activity against multiple tumor cell lines. XY153 also demonstrated good metabolic stability in vitro. These data indicate that XY153 may serve as a new and valuable lead compound for the development of potential therapeutics against acute myeloid leukemia (AML). All liver microsome assays were performed by Medicilon.

基于构效关系分析，合成了一种结构简化但具有优异防污活性的化合物。优化后的化合物通过美迪西合成
Biofouling poses one of the most serious problems to marine industry and aquaculture development. Five structurally similar compounds were isolated from the crude extract of a marine Streptomyces strain. Antifouling activities of these compounds and four other structurally-related compounds isolated from another marine Streptomyces species were compared to generate structure–activity relationship data. Based on structure–activity relationship analysis, another compound with a simplified structure but excellent antifouling activities was synthesized. The optimized compound was synthesized by Medicilon.

4-n-butyl resorcinol (4-nBR) is a highly effective tyrosinase inhibitor, and can be used in cosmetic product for depigmentation purpose. Its efficacy correlates with 4-nBR that absorbed by skin. In this study, skin distribution of 4-nBR within either human or pig skin ex vivo was studied and compared by three independent laboratories. Good agreement was observed in each compartment considering usual inter-lab variability. The percutaneous absorption and skin distribution studies were carried out by L'Oréal (lab A), Fudan University (lab B), and Medicilon (lab C).
