cyclo(RLsKDK)  (Synonyms: BK-1361)

cyclo(RLsKDK) (BK-1361) is a specific inhibitor of metalloproteinase ADAM8 with an IC₅₀ value of 182 nM. cyclo(RLsKDK) has potential applications in inflammatory diseases and cancer^[1].

cyclo(RLsKDK) promotes ADAM8 activation and CD23 shedding with IC₅₀ values of 120 nM and 182 nM, respectively^[2].
cyclo(RLsKDK) (200 nM; 0-120 h) increases activity of pro-ADAM8^[2].
cyclo(RLsKDK) (200 nM and 500 nM; 12 h) promotes the growth of Panc1_ctrl and Panc1_A8 cells^[2].
cyclo(RLsKDK) (500 nM) causes ERK1/2 phosphorylation in Panc1_ctrl and Panc1_A8 cells^[2].

cyclo(RLsKDK) (10 µg/g; i.p.; once weekly for 4 weeks) significantly reduces tumour load in mice which implant Panc1_ctrl or Panc1_A8 cells. cyclo(RLsKDK) improves the survival rate of pancreatic ductal adenocarcinoma (PDAC) mice, reduces soluble ADAM8 (sADAM8) content, pERK1/2 activation, and PDAC metastasis in the liver and lungs of PDAC mice^[2].
