Compound class: Synthetic organic
Comment: Compound 11 is a peptidyl-diphenyl phosphonate PR3 inhibitor, designed for enhanced inhibitory efficacy [1]. PR3 inhibitors have therapeutic potential for infectious and inflammatory diseases. Its peptide structure is represented as Bt-Val-Tyr-Asp-nValP(O-C6H4-4-Cl)2. Compound 11 is suitable for studies in primate models and human tissues, but is inactive vs. rodent PR3 [1].
