0 × 10-3 mg L-1). The molecular docking between compound 7f and RyRs of diamondback moth validated our molecular designation. Furthermore, the calcium imaging experiment explored the influence of compound 7o on the calcium homeostasis in the central neurons of the third larvae of oriental armyworm. The results of this study indicated that 7o is a potent novel lead targeting at RyRs.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) brutally perils physical and mental health worldwide. Unavailability of effective anti-viral drug rendering global threat of COVID-19 caused by SARS-CoV-2. In this scenario, viral protease enzymes are crucial targets for drug discovery. This extensive study meticulously focused on two viral proteases such as main protease (Mpro) and papain-like protease (PLpro), those are essential for viral replication. This review provides a detail overview of the targets (Mpro and PLpro) from a structural and medicinal chemistry point of view, together with recently reported protease inhibitors. An insight into the challenges in the development of effective as well as drug like protease inhibitors is discussed. Peptidomimetic and/or covalent coronavirus protease inhibitors possessed potent and selective active site inhibition but compromised in pharmacokinetic parameters to be a drug/drug like molecule. Lead optimization of non-peptidomimetic and/or low molecular weight compounds may be a better option for oral delivery. A masterly combination of adequate pharmacokinetic properties with coronavirus protease activity as well as selectivity will provide potential drug candidates in future. This study is a part of our endeavors which surely dictates medicinal chemistry efforts to discover effective anti-viral agent for this devastating disease. It remains unclear the clinical characteristics and prognosis of implantable cardioverter defibrillator (ICD) on prevention for sudden cardiac death (SCD) in Japanese patients with acute decompensated heart failure (ADHF) and reduced left ventricular ejection fraction (LVEF). We investigated the prevalence, clinical characteristics, and clinical outcomes in a contemporary large-scale Japanese ADHF registry. Among the consecutive 3785 patients hospitalized for ADHF and discharged alive in the Kyoto Congestive Heart Failure registry, we identified 1409 patients with reduced LVEF (ICD N = 115, non-ICD N = 1294). Patients in the ICD group were younger (69.3 ± 12.9/74.2 ± 13.6 years; p < 0.001), more likely to be men (84%/65%), and more often had a history of heart failure hospitalization (70%/36%; p = 0.001), cardiomyopathy as the underlying heart disease (51%/27%; p < 0.001), and previous serious ventricular arrhythmia (57%/3.8%; p < 0.001), and had lower LVEF (25.4±7.4%/29.5±6.9%; p < 0.001), nificant risk reduction for arrhythmic events, but not for mortality. This study elucidated the real-world features of ADHF patients between those with ICD and those without. ICD use in patients with ADHF and reduced LVEF as compared with non-ICD use was associated with significant risk reduction for arrhythmic events, but not for mortality.Asthenozoospermia (AZS), defined by reduced motility or absent sperm motility, is one of the main causes of male infertility. This condition may be divided into isolated AZS in the absence of other symptoms and syndromic AZS, which is characterized by several concurrent clinical symptoms. Sperm motility depends on fully functional flagellum, energy availability, and the crosstalk of several signaling pathways; therefore, mutations in genes involved in flagellar assembly and motile regulation can cause AZS. Thus, it is crucial to understand the genetic causes and mechanisms contributing to AZS. In this review, we summarize the current knowledge about the particular genes and mechanisms involved in intact flagellum, energy availability, and signaling transduction that could cause human AZS and dis
