Boronic acid/boronic ester fragment library

1,488 compounds

Boronic acid and boronic ester represent a relatively novel and promising chemical structure in drug design. Boronic acid exists in an sp²-hybridized state, possessing an empty p-orbital that can act as a Lewis acid to accept lone pairs from heteroatoms (O, N, or S). This Lewis acidity enables it to form reversible covalent bonds with amino acid residues such as lysine, serine, threonine, and histidine. Currently, five FDA-approved drugs containing boronic acid or boronic ester predominantly involve such covalent binding mechanisms in their interactions with target proteins. Furthermore, boronic acid can serve as a bioisostere for carboxylic acids, phosphates, and phenolic groups, utilized to improve pharmacokinetic properties and enhance drug efficacy.

To date, five boron-containing drugs have been approved by the FDA. The unique properties of boronic acids and boronic esters confer significant potential in drug design, with applications spanning cancer therapy (e.g., multiple myeloma), anti-infectives (e.g., fungal infections, tuberculosis), anti-inflammatory treatments (e.g., atopic dermatitis), antibacterial agents (e.g., carbapenem-resistant bacterial infections), and Reactive Oxygen Species (ROS)-responsive prodrugs, among others. The MCE Boronic Acid/Boronic Ester Fragment Library, which contains 1,488 compounds, serves as a valuable tool for the development of boron-containing drugs.

6A-Azido-6A-deoxy-β-cyclodextrin β-CDN3; 6A-deoxy-6A-azido-β-cyclodextrin		Azide
6A-Azido-6A-deoxy-β-cyclodextrin (β-CDN3) is a site-specifically modified β-cyclodextrin with a single azido group replacing the hydroxyl group at the C6 position. 6A-Azido-6A-deoxy-β-cyclodextrin forms a host-guest inclusion complex with Dexamethasone (HY-14648), localizing the drug within its hydrophobic cavity, which restricts the rotational mobility of the drug and places Dexamethasone in a less polar environment. 6A-Azido-6A-deoxy-β-cyclodextrin acts as a coupling agent to graft β-cyclodextrin onto thermosensitive nanogels via strain-promoted alkyne-azide cycloaddition (SPAAC). 6A-Azido-6A-deoxy-β-cyclodextrin also serves as a click chemistry reagent. It contains an azide group and undergoes copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules bearing an alkyne group. It also undergoes strain-driven alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups .

HY-Y0683A

Petrolatum (white)		Bases
Petrolatum (white) is mainly composed of hydrocarbons, possesses strong water resistance and moisturizing properties, and is commonly used as a pharmaceutical excipient. Petrolatum (white) penetrates into stratum corneum cells, improves skin barrier function, repairs epidermal structure, and reduces transepidermal water loss and the risk of skin damage. Petrolatum (white) induces the expression of antimicrobial peptides, innate immune genes, filaggrin and loricrin. Petrolatum (white) is used in research on atopic dermatitis and post-operative skin infections .

HY-Y0683B

Petrolatum (yellow)		Bases
Petrolatum (yellow) is mainly composed of hydrocarbons, possesses strong water resistance and moisturizing properties, and is commonly used as a pharmaceutical excipient. Petrolatum (yellow) penetrates into stratum corneum cells, improves skin barrier function, repairs epidermal structure, and reduces transepidermal water loss and the risk of skin damage. Petrolatum (yellow) induces the expression of antimicrobial peptides, innate immune genes, filaggrin and loricrin. Petrolatum (yellow) is used in research on atopic dermatitis and post-operative skin infections .

HY-174771

Human CCL11 mRNA		mRNA Chemokine & Receptors
Human CCL11 mRNA encodes the human C-C motif chemokine ligand 11 (CCL11) protein, a member of the CC subfamily. CCL11 is thought to be involved in eosinophilic inflammatory diseases such as atopic dermatitis, allergic rhinitis, asthma and parasitic infections.
