functional group

Phenolic compounds are usually referred to as a diverse group of naturally occurring compounds with multiple medical properties, such as antioxidants, antimicrobial properties. Those compounds are commonly found in food and plants. They have high synthetic, medicinal and industrial values. Polyphenols are compounds with multiple phenolic functionalities. Naturally occurring polyphenols are known to have biological activities for use as drugs, for example, in diseases like AIDS, heart ailments, ulcer formation, bacterial infection, mutagenesis and neural disorders.

MCE offers a unique collection of 1183 natural phenol compounds which is a useful tool for drug discovery as an important source of lead compounds.

Natural products are an attractive source with varied structures that exhibit potent biological activities, and desirable pharmacological profiles. The core scaffold of a natural product can also provide a biologically validated framework upon which to display diverse functional groups. Inspired by bioactive natural products, natural product-like compounds, occupying the same chemical space, are ideally suited to explore and to facilitate understanding of biological pathways.

MCE provides a unique collection of 581 natural product-like compounds that are structurally like Steroids, Tannins, Flavonoids, Quinones, Isoquinolines, etc. This library is an important source of lead compounds for drug discovery.

Peptides are a group of biologically active substances that are involved in various cellular functions of organisms. Peptides are often used in functional analysis, vaccine research and especially in the field of drug research and development. At present, more than 80 peptide drugs have reached the market for a wide range of diseases, including diabetes, cancer, osteoporosis, multiple sclerosis, HIV infection and chronic pain.

MedChemExpress (MCE) offers a comprehensive collection of 1354 peptides, including bioactive peptides, amino acid derivatives, and blocking peptides. MCE Peptide Library can be used for peptide library screening, peptide drug discovery, vaccine development, target verification, structural activity research, etc.

MCE 50K Diversity Library consists of 50,000 lead-like compounds with multiple characteristics such as calculated good solubility (-3.2<logP<5), oral bioavailability (RotB<=10), drug transportability (PSA<120). These compounds were selected by dissimilarity search with an average Tanimoto Coefficient of 0.52. There are 36,857 unique scaffolds and each scaffold 1 to 7 compounds. What’s more, compounds with the same scaffold have as many functional groups as possible, which make abundant chemical spaces. This exceptionally diverse library is highly recommended for random screening against new as well as popular targets based its novel, diverse scaffolds, abundant chemical spaces and the convenience for subsequent modification.

Natural products are an attractive source with varied structures that exhibit potent biological activities, and desirable pharmacological profiles. The core scaffold of a natural product can also provide a biologically validated framework upon which to display diverse functional groups. Inspired by bioactive natural products, natural product-like compounds, occupying the same chemical space, are ideally suited to explore and to facilitate understanding of biological pathways.

MCE 10K Natural Product-like Compound Library consists of 10,000 natural product-like compounds. Each compound has scaffold of natural products or Tanimoto coefficient >0.6 with natural products. The natural-likeness scoring of these compounds is >-2. What’s more, compounds in the library are drug-like and readily available for re-supply, making it a powerful tool for new drug research and development. It can be widely applied in high-throughput screening (HTS) and high-content screening (HCS).

MCE Carboxyl Magnetic beads (200 nm, 10 mg/mL) are characterized by superparamagnetism, fast magnetic response, abundant carboxyl functional groups, monodispersity, and submicron scale particle size. Biological ligands (proteins, peptides, oligonucleotides, drug molecules, etc.) can be covalently coupled to the surface of microspheres under the action of special chemical reagents (such as EDC).

MCE CHO Magnetic Beads (200 nm, 10 mg/mL) contain CHO functional groups, which react with primary amines on proteins or other molecules to form stable amide linkages，can covalently immobilize proteins for the affinity purification of antibodies, antigens and other biomolecules.

MCE NHS Magnetic Beads (200 nm, 10 mg/mL) contain N-hydroxysuccinimide (NHS) functional groups, which react with primary amines on proteins or other molecules to form stable amide linkages，can covalently immobilize proteins for the affinity purification of antibodies, antigens and other biomolecules.
