Conophyllidine, a bisindole alkaloid, is a selective M2 polarization inhibitor. Conophyllidine inhibits histone acetylation by targeting the histone acetyltransferase domain of the P300/CBP proteins. Conophyllidine inhibits IL-4-induced arginase with an IC50 of 0.31 μM. Conophyllidine effectively induces a phenotypic switch in tumor-associated macrophages (TAMs) from an anti-inflammatory to an inflammatory type, thereby enhancing cytotoxic CD8+ T cell recruitment and functionality within the tumor microenvironment. Conophyllidine can be used for the study of TAMs.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
