  Discovery of Quinoline Analogues as Potent Antivirals against Enterovirus D68 (EV-D68)

  摘要：

  Enterovirus D68 (EV-D68) is an atypical nonpolio enterovirus that mainly infects the respiratory system of humans, leading to moderate-to-severe respiratory diseases. In rare cases, EV-D68 can spread to the central nervous system and cause paralysis in infected patients, especially young children and immunocompromised individuals. There is currently no approved vaccine or antiviral available for the prevention and treatment of EV-D68. In this study, we aimed to improve the antiviral potency and selectivity of a previously reported EV-D68 inhibitor, dibucaine, through structure activity relationship studies. In total, 60 compounds were synthesized and tested against EV-D68 using the viral cytopathic effect assay. Three compounds 10a, 12a, and 12c were identified to have significantly improved potency (EC50 < 1 mu M) and a high selectivity index (>180) compared with dibucaine against five different strains of EV-D68 viruses. These compounds also showed potent antiviral activity in neuronal cells, such as A172 and SH-SY5Y cells, suggesting they might be further developed for the treatment of both respiratory infection as well as neuronal infection.

  This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having a quinoline (or similar) structure which function as antagonists of androgen receptor activity, and their use as therapeutics for the treatment of cancer (e.g., castration-resistant prostate cancer) and other conditions characterized with androgen receptor activity and/or androgen receptor expression.

  这项发明属于药物化学领域。具体而言，该发明涉及一类新型的小分子，其具有喹啉（或类似）结构，可作为雄激素受体活性拮抗剂，并且可用作治疗癌症（例如去势抵抗性前列腺癌）和其他与雄激素受体活性和/或雄激素受体表达有关的疾病的治疗药物。
