二、Reaction characteristics：

BK-1361（BK1361，cyclo-RLsKDK）是一种具有RLsKDK（s=D-丝氨酸）的环肽，其作为ADAM8的有效选择性抑制剂起作用，IC50为120nM，对ADAM 9,10,12没有显示出显着活性。在基于细胞的脱落测定中抑制CD23的脱落，IC50为182nM。 

BK-1361(BK1361, cyclo-RLsKDK) is a cyclic peptide with RLsKDK (s=D-serine) that functions as a potent, selective inhibitor of ADAM8 with IC50 of 120 nM; displays no significant activity against ADAM 9, 10, 12, 17 , as well as MMP-2, -9, and -14 at 10 uM; inhibit shedding of CD23 with IC50 of 182 nM in cell-based shedding assays, reduces migration/invasion of pancreatic cancer cells and less ERK1/2 and MMP activation, causes change in cell morphology; decreases tumour burden and metastasis of implanted pancreatic tumour cells and provides improved metrics of clinical symptoms and survival in Kras(G12D)-driven mouse model of PDAC.

三、Matters for use：

It is sensitive to light and temperature. In order to use the reagent effectively, the material should always be kept in a low temperature dry condition, away from light, and avoid frequent thawing and freezing.

四、storage conditions:

Store at - 20 ℃ as much as possible. If conditions permit, the material can be treated under inert gas to obtain better stability of the reagent.
