RESUMEN
A novel class of tetrahydropyrido-pyrazole thioether amines that display potency against human Cathepsin S have been previously reported. Here, further SAR investigations of the P3, P4, and P5 regions are described. In particular, 4-fluoropiperidine is identified as a competent P3 binding element when utilized in conjunction with a (S)-2-hydroxypropyl linker-containing P5 moiety and oxamide or sulfonamide P4 substitution.

Sleep is essential. Unfortunately, a significant portion of the population experiences altered sleep states that often result in a multitude of health-related issues. The regulation of sleep and sleep-wake cycles is an area of intense research, and many options for treatment are available. The following review summarizes the current understanding of normal and abnormal sleep-related conditions and the available treatment options. All clinicians managing patients must recommend appropriate therapeutic interventions for abnormal sleep states. Clinicians' solid understanding of sleep physiology, abnormal sleep states, and treatments will greatly benefit patients regardless of their disease process.
