藥物發現中的挑戰之一是識別高質量的先導化合物。此研究中PK結果表明L12可作為針對PDE5的先導化合物，進一步研究和開發。L12的PK分析通過尊龍凱時進行

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是一個潛在的鎮痛靶點。DFBTA是一種有效的ANO1抑制劑，具有優異的藥代動力學特性。體內PK測試通過尊龍凱時進行

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是一種有潛力的先導化合物，可用于開發針對急性髓系白血病。XY153在體外具有良好的代謝穩定性。所有肝微粒體測定均通過尊龍凱時進行

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.

基于構效關系分析，合成了一種結構簡化但具有優異防污活性的化合物。優化后的化合物通過尊龍凱時合成

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.
