Small molecule inhibitors

Small molecule inhibitors can bind to target proteins and reduce their biological activity and are often used as tools in biological and pharmacological research.

Small molecule inhibitors have become important tool drugs in life science research in recent years due to their significant advantages in the regulation of different cellular processes, such as cell cycle control, mitosis, signaling pathways, gene expression, migration, wound healing, apoptosis and autophagy.

TargetMol can provide over 12,000 small molecule inhibitors of 23 signaling pathways for research and development, such as:

Other than inhibitors, TargetMol provides small molecules including natural products, Protac, peptides, dyes etc.

Natural Products

Natural products can also be prepared by chemical synthesis and have played a central role in the development of the field of organic chemistry by providing challenging synthetic targets.

Naturally occurring compounds have been used medicinally for centuries and continue to be a rich source of novel therapeutics, including antibiotics and cancer drugs.

TargetMol offers more than 16,000 kinds of natural products, suitable for drug development, pharmacological research, stem cell differentiation, fingerprint research, quality research, and other fields

Life Science Kits

A reliable kit is an important factor to ensure the success of your experiment. TargetMol can provide cocktails and CCK8 for molecular biology experiments, which have many advantages, such as high sensitivity, good stability, and strong anti-interference ability. These properties can ensure the smooth progress of your experiments.

Compound libraries

A compound library or chemical library is a collection of stored chemicals usually used ultimately in high-throughput screening or industrial manufacture. Depending upon their scope (specific goal or diverse oriented goal) and design (chemical space or scaffold), our 170 compound libraries can be classified as Focused Bioactive Libraries, Natural Product Libraries, Fragment Libraries, and Diversity Sets.

Virtual Screening

Virtual screening (VS) is a computational technique used in drug discovery to search libraries of small molecules to identify those structures which are most likely to bind to a drug target, typically a protein receptor or enzyme. Compared with traditional experimental high-throughput screening (HTS), VS is a more direct and rational drug discovery approach and has the advantage of low-cost and effective screening. Virtual Screening can be used in retrospective studies or prospective studies.
