Synonyms: Sodium rhodizonate dibasic
Rhodizonic acid disodium (Sodium rhodizonate dibasic) is a transition metal-dependent pro-oxidant and lead detection agent that induces reactive oxygen species generation, DNA damage, and inhibits Aconitase activity. Rhodizonic acid disodium generates superoxide anion radicals in an iron (II)-dependent manner, leading to aconitase inactivation. Rhodizonic acid disodium also triggers hydroxyl radical-mediated DNA strand breaks and 8-OHdG formation via copper ion reduction. Rhodizonic acid disodium reacts with lead to form a scarlet precipitate, with the color intensity proportional to lead content, enabling qualitative or quantitative analysis of lead. Rhodizonic acid disodium can also be used for real-time visualization of the dynamic process of lead sequestration in the plant rhizosphere and evaluation of the effects of environmental factors such as soil type on the stability of lead-sequestering structures .

2'-O-MOE-U is a nucleic acid modification group (Phosphoramidite) with 3'-exonuclease inhibitory activity. 2'-O-MOE-U also exhibits gene silencing activity and double-stranded oligonucleotide stability. By forming steric interactions with 3'-exonuclease residues, 2'-O-MOE-U anchors the 3'-end of the siRNA guide strand in the hAgo2 PAZ domain, thereby regulating double-stranded thermal stability and enhancing base-pairing specificity. 2'-O-MOE-U does not induce IFNα production, can be incorporated at multiple sites of siRNA to enhance RNAi activity, and produces a synergistic effect with 2'-F modification. 2'-O-MOE-U has been widely used in studies related to breast cancer and other diseases .

PARP1-IN-58 is a ROS-responsive prodrug constructed based on a natural stilbene scaffold, and its active parent nucleus 24c acts as a selective PARP-1 inhibitor. PARP1-IN-58 only hydrolyzes to release the active parent compound in the high-ROS microenvironment of tumors; the active parent compound competitively binds to PARP-1 and blocks DNA single-strand damage repair, upregulates intracellular ROS levels, reduces mitochondrial membrane potential, and thereby induces cell cycle arrest and mitochondria-dependent apoptosis. PARP1-IN-58 exerts potent proliferation-inhibiting effects on BRCA-deficient breast cancer cells under simulated tumor oxidative stress conditions, and exhibits tumor growth inhibitory activity in breast cancer xenograft models. PARP1-IN-58 can be used in cancer-related research .

1,544 compounds

DNA damage response (DDR) is a fundamental mechanism for maintaining genomic stability. When DNA damage occurs, such as single- or double-strand breaks or replication fork stalling, cells rely on key proteins including ATM, ATR, PARP, and DNA-PK to sense the damage and transmit signals, thereby regulating DNA repair, cell-cycle arrest, and cell death. Inhibition of specific DNA repair or checkpoint pathways can prevent tumor cells from effectively repairing accumulated DNA damage, ultimately leading to tumor cell death.

MCE DNA Damage Repair Inhibitor Library contains 1,544 compounds, focusing on key nodes involved in DNA damage response and DNA repair. The library covers multiple DNA repair and cell-cycle checkpoint pathways, providing a systematic compound screening tool for research on precision oncology, synthetic lethality, drug resistance mechanisms, and chemo- or radiosensitization.

Synonyms: 8-Oxo-Deoxyguanosine triphosphate
8-Oxo-dGTP (8-Oxo-Deoxyguanosine triphosphate) is an oxidized guanine nucleotide formed by ROS-mediated oxidative modification of dGTP, and it also serves as a key substrate for 8-oxo-dGTP pyrophosphohydrolases (such as hMTH1 and E. coli MutT). 8-Oxo-dGTP acts as a DNA mutagen, inserts into nascent DNA and pairs with adenine and cytosine, inducing A:T to C:G transversion mutations.

HA2 peptide is a potent pH-responsive fusion peptide derived from hemagglutinin (HA), corresponding to the N-terminal fusion peptide domain consisting of 23 amino acid residues of HIV-1 gp41 envelope glycoprotein. HA2 peptide adopts a random coil structure under physiological pH conditions; in acidic endosomes, protonation of carboxyl groups reduces negative charge, inducing a transition to an α-helical conformation that can fuse with and destabilize the endosomal membrane. After binding to membranes, the N-terminal and middle regions of HA2 peptide mainly adopt a β-strand conformation, while the C-terminal region remains unstructured. HA2 peptide induces lipid mixing and promotes aqueous content leakage from large unilamellar vesicles whose lipid composition matches that of HIV-1 viruses and target T cells. HA2 peptide is anionic and can bind to cationic peptides to achieve siRNA condensation. HA2 peptide can be used in studies related to cancer and human immunodeficiency virus (HIV) infection .
