CRP, an acute phase serum protein synthesized in response to inflammatory cytokines, produces antitumor effects in animals. The fragment CRP (174-185) (RS-83277) shows similar activity by significantly enhancing the tumoricidal activity of human monocytes and alveolar macrophages in vitro.

RR-11a 类似物是一种有效的选择性天冬酰胺酰内肽酶 (AE) (Legumain) 抑制剂（对于阴道毛滴虫中的 AE1、蓖麻硬蜱中的 AE 和曼氏血吸虫中的 AE，IC50 值分别为 4.5 nM、4.5 nM 和 31 nM）。

RGD Trifluoroacetate is a tripeptide that effectively triggers cell adhesion, addresses certain cell lines and elicits specific cell responses; RGD Trifluoroacetate binds to integrins.RGD Trifluoroacetate is the most effective and most often employed peptide sequence for stimulated cell adhesion on synthetic surfaces. There are 24 integrins binding to ECM molecules in a RGD dependent manner: α3β1, α5β1, α8β1, αIIbβ3, αvβ1, αvβ3, αvβ5, αvβ6, αvβ8, and to some extent α2β1 and α4β1.
