rad51 in 2

Emzadirib (RAD51-IN-2) is a potent RAD51 inhibitor with potential anticancer activity for the study of DNA damage repair.

(D(CH2)51,Tyr(Me)2,Thr4,Orn8,des-Gly-NH29)-Vasotocin, serving as an oxytocin receptor antagonist, effectively nullifies the augmentation of inhibitory postsynaptic currents in CA1 pyramidal neurons by oxytocin [1].

SARS-CoV-2-IN-51 (S-10), a lead compound for Omicron fusion inhibition, demonstrates potent activity against Omicron and other SARS-CoV-2 variants, with EC50 values ranging from 0.82-5.45 μM. It functions by directly interacting with the spike (S) protein in the prefusion state [1], thereby preventing viral entry.

(d(CH2)5[Tyr(Me)2, Dab5]AVP), a vasopressin V1a receptor-specific antagonist, demonstrates a pA2 value of 6.71 [1].

(d(CH2)51,Tyr(Me)2, Orn8)-Oxytocin (OVT) is an antagonist of the oxytocin receptor that finds application in the study of neurological diseases [1].

Selective vasopressin V1A receptor antagonist. Inhibits vasopressin and oxytocin-induced increases in intracellular calcium concentrations in vitro (IC50 values are 5 and 30 nM respectively). Exhibits potent and prolonged antivasopressor activity and indu

RI-2 is an optimized RAD51 inhibitor with an IC50 of 44.17 μM in the standard DNA binding assay; specifically inhibits HR(Homologous recombination) repair in human cells.

Phosphoramide mustard cyclohexanamine is the major metabolite for Cyclophosphamide , with anticancer activitiy. Phosphoramide mustard cyclohexanamine induces DNA adduct formation in ovarian granulosa cells, induces DNA damage and elicits the ovarian DNA repair response[1][2]. Phosphoramide mustard cyclohexanamine causes cytotoxicity through forming cross-linked DNA adducts which inhibit DNA strand separation during replication[1].Phosphoramide mustard cyclohexanamine destroys rapidly dividing cells by forming NOR-G-OH, NOR-G and G-NOR-G adducts with DNA, potentially leading to DNA damage[1].Phosphoramide mustard cyclohexanamine (3-6 μM; 48 hours) reduces cell viability in rat spontaneously immortalized granulosa cells (SIGCs)[1].Phosphoramide mustard cyclohexanamine (3-6 μM; 24-48 hours) induces DNA adduct formation[1].Phosphoramide mustard cyclohexanamine (3-6 μM; 24-48 hours) induces ovarian DNA damage in rat ovaries[1].Phosphoramide mustard cyclohexanamine increases DNA damage responses (DDR) gene (Atm, Parp1, Prkdc, Xrcc6, Brca1, Rad51) mRNA expression level[1].Phosphoramide mustard cyclohexanamine (3-6 μM; 24-48 hours) increased DDR proteins[1]. Cell Viability Assay[1] Cell Line: SIGCs Phosphoramide mustard cyclohexanamine (2.1-20.7 mg/kg; i.p.; daily; for 5 days) inhibits subcutaneous tumor growth in rats[2].Phosphoramide mustard cyclohexanamine (86.0 mg/kg; i.v.) has a plasma disappearance half-life of 15.1 minutes[2].

RI(dl)-2 TFA is a potent and selective RAD51-mediated D-loop formation inhibitor with an IC 50 of 11.1 μM which also inhibits homologous recombination(HR) activity in human cells with IC50 of 3.0 μM[1].
