Immunology/Inflammation Compound Library

5,514 compounds

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. Inflammation is also the body's attempt at self-protection to remove harmful stimuli and begin the healing process. It’s part of the body's immune response. The immune system recognizes damaged cells, irritants, and pathogens, and inflammation begins the healing process. Inflammatory abnormalities are a large group of disorders that underlie a vast variety of human diseases. The immune system is often involved with inflammatory disorders, demonstrated in both allergic reactions and some myopathies, with many immune system disorders resulting in abnormal inflammation.

MCE designs a unique collection of 5,514 compounds that are useful tool for Immunology/Inflammation research or autoimmune inflammatory diseases drug discovery.

HY-151837

H-L-Phe(4-NH-Poc)-OH hydrochloride		Alkynes
H-L-Phe(4-NH-Poc)-OH (hydrochloride) is a click chemistry reagent containing an azide group. Used as a modified Phe or Tyr analogue in protein and peptide biosynthesis. Propargyloxycarbonyl, commonly abbreviated as Poc or Pryoc, can either be used as alkyne component for standard Click conjugation or in combination with tetrazine linkers in copper-free Diels-Alder type Click reactions. It also has applications as unusual protecting group for amines, hydroxy functions and as esters. All 3 are stable to neat TFA, but can be cleaved at ambient temperature with Co2(CO)8 in TFA:DCM. Deprotection with other transition metals like palladium have also been reported . H-L-Phe(4-NH-Poc)-OH (hydrochloride) is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

DSPE-PEG-Amine, MW 3400 ammonium DSPE-PEG-NH2, MW 3400 ammonium		Pegylated Lipids
DSPE-PEG-Amine, MW 3400 (ammonium) is a phosphoethanolamine involved in the synthesis of liposomes for delivery systems. The amino group of DSPE-PEG-Amine, MW 3400 (ammonium) can be converted to aromatic aldehydes by reacting with acetone-protected aromatic hydrazines on the surface of bovine carbonic anhydrase (BCA) molecules. Liposomes form a liposome-BAH-BCA conjugate by forming a bisarylhydrazone (BAH) with the target enzyme molecule. The conjugate catalyzes the hydration of carbon dioxide to bicarbonate.
