Anemia resulting from the reduced expression of erythropoietin (EPO) is a common complication of patients with chronic kidney diseases (CKD). Hypoxia inducible transcription factor-α (HIF-α), which adapts cellular hypoxia condition, regulates the expression of many downstream genes including the EPO gene. Hypoxia inducible transcription factor prolyl hydroxylase 2 (HIF-PHD2), as the key regulator of hypoxia response, is function of hydroxylating specify proline residues of HIF-α, which may lead to the degradation of HIF-α and eventually cause disenabling the expression of erythropoietin. Therefore, it is valid to improve anemia by inhibiting HIF-PHD2. In-vitro screening plays a vital role in searching for novel small molecule HIF-PHD2 inhibitors, thus, this review classified in-vitro screening methods which are used to hit novel HIF-PHD2 inhibitors.
