OD 36 hydrochloride is a potent inhibitor of RIPK2 kinase with an IC50 value of 5.3nM [1]. OD 36 hydrochloride mimics the interaction between the ATP adenine ring and the hinge region of RIPK2 KD, and utilizes the interaction between the cyclic linker group and the hydrophobic posterior pocket as well as the ribose binding region, thereby enhancing the affinity and selectivity for RIPK2[2]. OD 36 hydrochloride has been widely used in mouse peritonitis models to alleviate inflammation[3].
In vitro, OD 36 hydrochloride treatment (0.5μM) for 21 days significantly inhibited the osteogenic and chondrogenic differentiation induced by activin A in ATDC5 cells expressing mutant R206H ALK2 [4]. The 5.3nM OD 36 hydrochloride treatment for 24 hours significantly inhibited the invasion and metastasis of K7M2 cells promoted by macrophages[5].
In vivo, OD 36 hydrochloride treatment via intraperitoneal injection at a single dose of 6.25mg/kg can reduce the cell infiltration in a muramyl dipeptide (MDP)-induced peritonitis mouse model [6].

| Cell experiment [1]: | |
Cell lines | ATDC5 cells |
Preparation Method | ATDC5 cells were transduced with the same titer of adenoviral particles in the presence of Polybrene (4mg/ml), encoding for either the ALK2wt‐HA or ALK2R206H‐HA. ATDC5 cells were trypsinized and washed once with PBS. There were 3×105 cells counted per micromass, and resuspended in 10μl of culture medium. Very carefully, 100‐μl drops were deposited in the center of the well in a 24‐wells plate and placed in the incubator for 2 hours. Next 500μl of DMEM‐F12 5% fetal bovine serum (FBS) containing 1× ITS were carefully added to the wells. After 24 hours, the medium was replaced by DMEM‐F12 5% FBS containing 1× ITS, supplemented with activin A (100ng/ml), and DMSO, LDN‐193189, OD 36 hydrochloride, or OD52 (0.5μM). The cells were incubated for 21 days before further analysis, refreshing the medium every 5 days. Finally, the cells were washed and pictures acquired using a microscope with 10× magnification. |
Reaction Conditions | 0.5μM; 21 days |
Applications | OD 36 hydrochloride treatment significantly inhibited the osteogenic and chondrogenic differentiation induced by activin A in ATDC5 cells expressing mutant R206H ALK2. |
| Animal experiment [2]: | |
Animal models | C57BL/6 mice |
Preparation Method | C57BL/6 mice were housed in an air-conditioned room with a 12h light/dark cycle and received standard laboratory rat chow and tap water. Rats were allowed 7 days to adjust to their new environment. C57BL/6 mice were given vehicle or 6.25mg/kg of Gefitinib or OD 36 hydrochloride intraperitoneal in a 500μl volume. Thirty minutes later, mice were injected with 150μg of MDP intraperitoneal. Four hours later, mice were sacrificed and a peritoneal lavage using 5ml of PBS was performed. |
Dosage form | 6.25mg/kg for once; i.p. |
Applications | OD 36 hydrochloride treatment reduced the cell infiltration in a muramyl dipeptide (MDP)-induced peritonitis mouse model. |
