PIC1 PA, a peptide consisting of 15 amino acids, serves as an effective analog of PIC1 that inhibits complement activation mediated by the classical pathway. Functionally, PIC1 PA interferes with the interaction between the C1s-C1r-C1r-C1s/MASPs and the collagen-like region (CLR) of C1q/MBL. It specifically binds to the CLR of C1q, with an average equilibrium dissociation constant (KD) of 33.3 nM when binding purified C1q.

PIC1 PATFA is the trifluoroacetate form of PIC1 PA. PIC1 PA TFA is a peptide composed of 15 amino acids and serves as an effective PIC1 analog capable of inhibiting complement activation mediated by the classical pathway.

PDE12-IN-1 is a powerful and specific inhibitor of PDE12, exhibiting a pIC 50 value of 9.1 for enzyme inhibition. It effectively enhances levels of 2′,5′-linked adenylate polymers (2-5A), with a pEC 50 value of 7.7. Additionally, PDE12-IN-1 demonstrates antiviral activity.

IL-17A modulator-1 is an effective inhibitor of IL-17A activity, exhibiting a pIC 50 value of 8.2. This compound holds great promise for studying diseases and disorders that involve the modulation of IL-17A, such as immune-related diseases, autoimmune pathologies, cancer, and neurodegenerative disorders.

A1AR antagonist 6 (compound 15) is a potent and selective inhibitor of the A1 adenosine receptor (A1AR), exhibiting a pKi of 7.13 and a pIC50 of 6.38[1].

A1AR antagonist 5 (compound 20) is a potent and selective inhibitor of the A1 adenosine receptor (A1AR) with a pKi of 6.11 and a pIC50 of 5.83 [1].

NBI 35965 hydrochloride is a selective CRF1 (corticotropin-releasing factor receptor 1) antagonist that is both orally active and capable of penetrating the brain. It possesses a K i value of 4 nM and a pK i of 8.5, and does not affect CRF2. This compound effectively diminishes CRF or stress-triggered ACTH (adrenocorticotropic hormone) production in vivo, demonstrating pIC 50 values of 7.1 and 6.9. Additionally, NBI 35965 hydrochloride exhibits anxiolytic properties [1] [2].

Tyrosinase-IN-17 (Compound 5b), characterized as a lipophilic, skin-permeable, and non-cytotoxic tyrosinase inhibitor (pIC 50 = 4.99), is suited for research into melanin-related diseases, including melanoma and melanogenesis [1].
