rlx

RLX (PD 139530) is a PI3K/Akt/FoxO3a signal inhibitor with anticancer activity against tumour cell lines such as colon cancer, inducing sub-G1 arrest and mitochondrial potential loss, thereby inhibiting tumour growth. RLX also exhibits antitussive and anti-asthmatic activity, reducing eosinophils and total lymphocytes in bronchoalveolar lavage (BAL) fluid, and exhibits toxicity toward A549 cells.

RLX HCl is a narcissus ketone analogue with anticancer activity that inhibits tumour proliferation by suppressing the PI3K Akt FoxO3a signalling pathway in experimental colon cancer, downregulating the p110α and p85 subunits of PI3K in HCT-116 cells, and exhibiting antiproliferative effects.

RLX-33 is a potent and selective antagonist of relaxin family peptide 3 (RXFP3) that crosses the blood-brain barrier and also blocks relaxin 3-induced ERK1/2 phosphorylation. RLX-33 can block the increase in food intake induced by the RXFP3 selective agonist R3/I5 in rats.RLX-33 can be used to study the metabolic syndrome.

PRLX-93936 HCL is an analog of erastin and demonstrated synergistic effects against non-small cell lung cancer (NSCLC) cells with cisplatin.

PRLX-93936 is an analog of erastin that has antitumor activity. It inhibits the hypoxia-inducible factor 1 (HIF-1) signaling pathway under hypoxic conditions (IC50 = 0.09 μM in a cell-based reporter assay). PRLX-93936 (1 μM) also inhibits hypoxia-induced increases in HIF-1α expression in ME-180 cervical cancer cells. It inhibits the growth of HT-1080 fibrosarcoma, OVCAR-5 ovarian cancer, BJELR tumorigenic primary fibroblast, and PANC-1 pancreatic cancer cells with IC50 values of less than 100 nM. PRLX-93936 inhibits tumor growth in PANC-1 and HT-1080 xenograft models when administered at a dose of 50 mg/kg and induces tumor regression when administered at a dose of 100 mg/kg.
