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 compound libraries can be classified as Focused Bioactive Libraries, Natural Product Libraries, Fragment Libraries, and Diversity Sets. These libraries have been extensively validated in our in- house biological assays and widely employed by research institutions and pharmaceutical companies in complementary screening strategies. Identifying novel and robust chemical starting points remains one of the biggest challenges in drug discovery today. Over the last decade, it has been common practice during the early stage of a project to screen vast numbers of compounds that cover larger section of chemical space evenly (diversity-led paradigm) in high-throughput assays in order to identify those chemicals which have the potential to modulate the target of interest. The costly nature of such mass screening, the consequent need to use reductionist assays that are optimized primarily for scale and speed, and the increasing realization that drug property space is far from random has more recently led to the use of smaller, higher quality screening collections (target-led approaches). All of these compound libraries and their screening approaches have their own particular advantages and disadvantages.

Focused Bioactive Libraries

Generally higher hit rates are observed in screening focused bioactive libraries when compared with the screening of diverse sets, and the hit clusters obtained from a successful focused library screening campaign usually exhibit discernable structure-activity relationships that facilitate follow up of these hits. Focused Bioactive Libraries is a powerful tool for drug screening, cell induction, drug repurposing, mechanism research, target identification, positive control and other related research fields.

General Bioactive Libraries : General Bioactive Libraries: Covering nearly 20,000 known biologically active small molecules, including Bioactive Compound Library, Approved Drug Library, Clinical Compound Library, FDA-Approved Drug Library, and Featured Novel Bioactive Compound Library.

Natural Product Libraries

Natural products are an unsurpassed source of chemical diversity and an ideal starting point for any screening program for pharmacologically active small molecules. Historically, natural products have been the most successful source of new drugs. Natural Product Libraries is a powerful tool for cell induction research and the drug screening focused on unique natural structures along with new bioactivity.

Natural Product Library for HTS : The TargetMol natural product libraries are continuously updated and contain structurally novel and active natural products from plants, animals, microorganisms and marine organisms. Our natural product libraries can be used for high-throughput screening, high-content screening, new drug development, pharmacological research and other fields, and are globally cited by highly-scored journals.

Characteristic Natural Product Libraries : Natural products originate from various sources, including animals, plants, microorganisms, etc. With their diverse structures, natural products cover over 30 types of unique compound structures, including flavonoids and alkaloids, and exhibit various biological activities such as anti-cancer and anti-inflammatory characteristics. Based on the number of genes, it has been estimated that the plant kingdom contains more than 200,000 different metabolites with values for single species ranging between 5,000 and 15,000, values that are significantly greater than those of microorganisms (∼1,500) and animals (∼2,500). We created several Characteristic Natural Product Libraries based on their biogenesis and the source they originate from (Alkaloid Natural Product Library, Flavonoid Natural Product Library, Polyphenolic Natural Product Library, Terpene Natural Product Library, Selected Plant-Sourced Compound Library, and Microbial Natural Product Library) as well as their specific applications (Anti-Inflammatory Traditional Chinese Medicine Compound Library, Anti-Tumor Natural Product Library, and Food as Medicine Compound Library). In addition, we can formulate customized natural product library for our customers with specific needs.

Natural Product Derivatives Libraries : Natural products have been a treasure trove for new drug development, a source of new structures and new ideas. Since the 1940s, nearly 75% of the newly discovered small molecule anti-cancer drugs are associated with natural products, and 40 natural product derivatives were approved between 1998 and 2009. Natural products and their derivatives are potent tools for studying and modulating protein function and natural product-related drug designs.

Natural Product Library for CADD : Natural products are known for their general high bioactivity and representative chemical backbones. With years of experience in the hit discovery-to-lead optimization process, Targetmol has built a collection of Natural Product Libraries that can be used for CADD. The libraries comprise a leading number of natural products and their derivatives, all of which are in-house to be supplied by Targetmol for HTS and HCS. By implementing CADD to in-house compound screening, we believe new drug discovery would be more efficient and cost-effective.

Drug-like Compound Libraries

This is a collection of up to 12 million small molecules, an effective tool for scientific research and new drug target screening. It is a high-quality choice for high-throughput screening (HTS), high-content screening (HCS), and virtual screening. There are currently 50 million compounds commercially available in the global market, from which we have selected products with reliable quality and good drug-like diversity to form highly cost-effective drug-like compound libraries, providing experimental samples for our customers. Drug-like compound libraries are TargetMol's core products with many operational cases and accumulated rich professional experience. If you would like to build your own customized HTS compound library, please feel free to contact our technical support.

Fragment Libraries

Fragment-based drug discovery (FBDD) has emerged in the past decade as an alternative approach to traditional lead identification via high-throughput screening (HTS). Unlike HTS, FBDD identifies smaller compounds, the “fragments,” which bind to different parts of a biological target. FBDD has played a role in discovery of 2 approved drugs and at least 30 drugs that are in various stages of clinical development. In response to this evident trend in drug discovery, TargetMol has designed its Fragment Libraries, including a selection of unique fragment subsets: Drug-Fragment Library, High Solubility Fragment Library, and Featured Fragment Library.
