Valeryl-L-carnitine is a short-chain acylcarnitine and a derivative of L-carnitine . Valeryl-L-carnitine levels increase in the serum of rhesus monkeys following exposure to 7 and 10 Gray units (Gy) of ionizing radiation.[1]

XJB-5-131 is a synthetic, bi-functional antioxidant specifically designed to target mitochondria for the scavenging of reactive oxygen species (ROS) and electrons, thereby acting as a radical scavenger. Additionally, it serves as an effective protector and mitigator against ionizing irradiation for cord blood mononuclear cells (CB MNCs).

Tirapazamine (Win59075) 是抗癌剂，对实体瘤中的缺氧细胞具有选择性细胞毒性，促使 DNA 中的单链和双链断裂，碱基损伤和细胞死亡。

SU-11752 is a potent and selective DNA-PK inhibitor. Inhibition kinetics and a direct assay for ATP binding showed that SU11752 inhibited DNA-PK by competing with ATP. SU11752 inhibited DNA double-strand break repair in cells and gave rise to a five-fold sensitization to ionizing radiation. At concentrations of SU11752 that inhibited DNA repair, cell cycle progression was still normal and ATM kinase activity was not inhibited.

Etanidazole (SR-2508) is a 2-nitroimidazole drug with radiosensitizing properties. Etanidazole depletes glutathione and inhibits glutathione transferase, thereby enhancing the cytotoxicity of ionizing radiation. This agent may also be useful as an imaging agent for identifying hypoxic, drug-resistant regions of primary tumors or metastases. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

NU1085 is a potent poly(ADP-ribose) polymerase (PARP) inhibitors have been developed that potentiate the cytotoxicity of ionizing radiation and anticancer drugs. The biological effects of NU1085 [Ki = 6 nM], in combination with temozolomide (TM) or topotecan (TP) have been studied in 12 human tumor cell lines (lung, colon, ovary, and breast cancer). Cells were treated with increasing concentrations of TM or TP +/- NU1085 (10 microM) for 72 h.

Reltecimod TFA（AB-103 TFA）是一种CD28(T淋巴细胞受体)模拟物，作为CD28的拮抗剂，能够抑制一系列细菌病原体对t细胞的刺激从而减轻急性炎症，用于治疗坏死性软组织感染（NSTI）。
