rad51-in-1

RAD51-IN-1 是 B02 的衍生物，是一种RAD51的有效抑制剂，可研究癌症。

TT-232 TFA（147159-51-1 free base）诱导人结肠肿瘤细胞系 SW620 中磷酸酪氨酸磷酸酶活性的双相激活。

BRCA2-RAD51-IN-1（Compound 46）作为一种BRCA2-RAD51抑制剂，显示出EC50为28 μM的活性，并且具备抗肿瘤特性。

FIZZ-1 (32-51) (mouse) 是一种富含半胱氨酸的分泌性蛋白，主要在过敏性气道炎症中被巨噬细胞、支气管上皮细胞及II型肺泡上皮细胞高度表达，具有对肺成纤维细胞的抗凋亡功能，广泛应用于过敏性肺炎的研究领域。

RS-1 是一种 RAD51 的激活剂，同时可增强 CRISPR Cas9 的活性。

RAD51-IN-8，一种新型 RAD51 结合剂，是一种RAD51-BRCA2抑制剂，可在微摩尔范围内抑制 RAD51-BRCA2 蛋白的相互作用。RAD51-IN-8 也是一种蛋白质-蛋白质相互作用 (PPI) 抑制剂。RAD51-IN-8 对 H4A4 具有抑制活性，EC50值为19 μM。

RI(dl)-2 TFA 是一种有效的选择性 RAD51 介导的 D 环形成 (RAD51-mediated D-loop formation) 抑制剂，IC50为 11.1 μM，并抑制人细胞中的同源重组 (HR) 活性，IC50为 3.0 μM。

CAY10760 is an inhibitor of the protein-protein interaction between RAD51 recombinase and BRCA2 (EC50= 19 μM in a cell-free competitive ELISA).1It decreases homologous recombination by 54% in wild-typeBRCA2-expressing BxPC-3 pancreatic cancer cells when used at a concentration of 20 μM. CAY10760 (20 μM) decreases proliferation of BxPC-3, as well as mutantBRCA2-expressing Capan-1, cancer cells when used alone or in combination with the poly(ADP-ribose) polymerase (PARP) inhibitor olaparib . 1.Bagnolini, G., Milano, D., Manerba, M., et al.Synthetic lethality in pancreatic cancer: Discovery of a new RAD51-BRCA2 small molecule disruptor that inhibits homologous recombination and synergizes with olaparibJ.

BRC4wt是一种从人类BRCA2的BRC4重复区(1521-1536)衍生而来的乙酰化肽，并且是BRCA2与RAD51之间的蛋白质-蛋白质相互作用的抑制剂。当与阳离子穿膜肽(Arg)9结合时，BRC4wt缩短了体外DNA复制轨迹长度，并降低了由DNA拓扑异构酶I抑制剂坎普特西汀引起的DNA损伤的同源修复频率，同时也增强了聚(ADP-核糖)聚合酶(PARP)抑制剂奥拉帕尼在HeLa人类宫颈癌细胞和U2OS人类骨肉瘤细胞中诱导的细胞死亡，但在非癌症细胞hTERT RPE-1、MRC-5或MCF-10A中则不然。

NHEJ inhibitor-1 (Compound C2) 是一种三功能 Pt(II) 复合物，可缓解非同源末端连接 (NHEJ)/同源重组 (HR) 相关的双链断裂 (DSB) 修复，从而避免非小细胞肺对顺铂的耐药性。NHEJ inhibitor-1 抑制损伤修复蛋白 Ku70 和 Rad51，从而使肿瘤对活性分子重新敏感。NHEJ inhibitor-1 还诱导 ROS 产生和MMP 降低。

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].
