Bioactive Compound Library Max is a collection of 25682 compounds with biological activity that elicit biological responses in cells, tissues and even individuals. It includes drug molecules that are in preclinical studies, clinical-phase studies and those that are already on the market. With clear targets and comprehensive information, it is ideal for drug repurposing, cell induction and differentiation, and protein target identification in biochemical mechanistic studies.

Because of the clear activity and known targets, many scientists will select small molecules from the Bioactive Compound Library that can be used for cell induction and differentiation. By the combined actions of a single or several small molecules, molecules capable of inducing various somatic cells into induced pluripotent stem cells, neural precursor cells, cardiomyocytes, etc. have been screened; there have even been successful trials of induced differentiation in vivo using combinations of small molecules.

The Bioactive Compound Library Max is a more extensive version of the Bioactive Compound Library (L4000), with the addition of TargetMol's unique and novel compounds (Part B), all of which have clear targets and have been tested for activity at the cellular level. Therefore, it has more novel structures than approved drug libraries and leads to easier active compounds discovery than drug-like compound libraries.
