The diseases-related complications and causes are threaded. Accordingly, the preparation of one drug with multiple targets is very pressing. In this context, the three series of pyrazole-based derivatives 7a-c, 9a-c, and 11a-c were designed and synthesized by using 5-amino-pyrazoles 3a-c as starting materials. The structures of various products 7a-c, 9a-c, and 11a-c were characterized by using various devices (elemental analysis and spectral tools). The biological activities of pyrazole-based products 7a-c, 9a-c, and 11a-c were estimated as antioxidant, anti-diabetic, anti-Alzheimer, and anti-arthritic. The estimation results showed that the two products 7c and 11a displayed powerful biological activities. In silico analysis (physicochemical, drug-likeness, and toxicity properties) of the two products 7c and 11a was performed. This research could be valuable for the exploration of one drug with multiple targets.
