Melanocortin (MC) 3-MSH (Melanocyte-Stimulating Hormone) is believed to signal through the MC 3 receptor. It induces a sustained increase in intracellular free calcium levels ([Ca2+]i) in a subpopulation of pituitary cells. Most of the cells responding to 3-MSH express more than one pituitary hormone mRNA. The effect of 3-MSH is blocked by SHU9119, a MC3R and MC4R antagonist, in only 50% of the responsive cells, suggesting that in half of these cells the mediating receptor is not the MC3R. Low picomolar doses of 3-MSH increase [Ca2+]i in the growth hormone (GH)- and prolactin (PRL)-secreting GH3 cell line.

Zolbetuximab(IMAB362) is a monoclonal antibody that specifically targets Claudin-18.2.Zolbetuximab has potential antitumor activity, mediating killing of Claudin-18.2-positive cells through an immune effector mechanism.

JAMM protein inhibitor 2?is an inhibitor of JAMM protease and can be used for anticancer studies. The IC50s are 10 μM, 46 μM, and 89 μM for thrombin, Rpn11, and MMP2, respectively.
