Laminaran is a β-1,3-glucan isolated from brown algae, often serving as a typical ligand for Dectin-1. It possesses anti-cancer, immune-modulating, and radiation-protective properties. Laminaran can be catalyzed by glucanase. In in vitro and in vivo experiments, Laminaran has demonstrated anti-tumor activity and may be used for severe cancers.

L-Histidine (L-(-)-Histidine) is a semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair, L-Histidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. Histamines play many roles in immunity, gastric secretion, and sexual functions. L-Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals.

Cystamine dihydrochloride is a radiation-protective agent. It also protects against carbon tetrachloride liver damage.

Dioxybenzone (Benzophenone-8) is an organic agent that blocks UVB and short-wave UVA ultraviolet radiation.

Ornidazole (Tiberal) is a nitroimidazole antiprotozoal agent used in ameba and trichomonas infections. It is partially plasma-bound and also has radiation-sensitizing action.

Meclizine dihydrochloride (NSC28728) is a histamine H1 antagonist used in the treatment of motion sickness, vertigo, and nausea during pregnancy and radiation sickness.

Potassium iodide is used as the treatment of overactive thyroid and as protection of the thyroid gland from the influences of radiation from swallowed or inhaled radioactive iodine. It may be used after accidental exposure to radioactive iodine or before and after administration of medicine containing radioactive iodine.

Bismaleimide (XU 292A) has heat resistance, oxidation resistance and radiation resistance, and can be used to prepare electrical insulation materials, wear-resistant materials, reinforced plastic additives, grinding wheel adhesives, etc.

Ondansetron hydrochloride (Zofran) is a serotonin 5-HT3 receptor antagonist, used to prevent nausea and vomiting caused by cancer chemotherapy, and radiation therapy.

10-Hydroxydecanoic Acid (NSC 15139) has antibacterial, anti - cancer and anti - radiation activity.

L-Cystine (Cystine Acid) is not considered one of the 20 amino acids, L-Cystine (Cystine Acid) is a sulfur-containing derivative obtained from oxidation of cysteine amino acid thiol side chains. It functions as an antioxidant and protects tissues against radiation and pollution, slowing the aging process. It also aids protein synthesis. L-Cystine (Cystine Acid) is abundant in many proteins of skeletal tissues and skin, and found in insulin and digestive enzymes chromotrypsinogen A, papain, and trypsinogen.

Calyculin A ((-)-Calyculin A), a toxicant in the Japanese marine sponge CDiscodermia calyxC, is a selective and potent inhibitor of protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A), inducing hyperactivation of cryopreserved bovine spermatozoa and inhibiting radiation-induced gammaH2AX DNA repair disease in human lymphocytes. gammaH2AX DNA repair foci in human lymphocytes.

(Rac)-LB-100, a novel Protein Phosphatase 2A (PP2A) inhibitor, sensitizes malignant meningioma cells to the therapeutic effects of radiation

Tirapazamine (Win59075) is a potent cytotoxic agent under hypoxic conditions, can induce apoptosis by inducing breaks in single and double-stranded DNA, as well as chromosomal breaks. The compound sensitizes cells to other ionizing radiation and other cytotoxic agents like cisplatin.

Rusalatide acetate (TP508 amide acetate), a regenerative peptide, mitigates radiation-induced gastrointestinal injury by activating stem cells and preserving mucosal integrity.

RGW 611, a morpholine derivative, enhances radiation effects and induces cell death in hypoxic V79-379A cells.

Methylproamine is a DNA-binding radioprotector that acts by repairing transient radiation-induced oxidative species on DNA.

Romurtide is a synthetic muramyl dipeptide analog and can be used for the prophylaxis of leukocytopenia during radiation therapy.

Photoswitchable PAD inhibitor is a photoactivated protein arginine deiminase (PAD) inhibitor and a derivative of BB-Cl-amidine that contains an azobenzene photoswitch allowing optical control of PAD activity.1 Without photoactivation, it is a weak inhibitor of PAD2 (IC50 = >100 μM) and is less potent than BB-Cl-amidine in inhibiting citrulline production in vitro (kinact/KIs = 2,300, 600, 1,000, and 10,510 M-1min-1 for PAD1-4, respectively) and does not inhibit histone H3 citrullination in HEK293T cells overexpressing PAD2 when used at concentrations up to 100 μM. However, it can rapidly be photoactivated with UV-A radiation to the more active cis-isomer, which is an irreversible, competitive inhibitor of histone H3 citrullination with an IC50 value of 9.1 μM.References1.
