PHT-427 is a dual Akt and PDPK1 inhibitor with Ki of 2.7 μM and 5.2 μM, respectively.

pht-427 is an inhibitor of akt and pdpk1 (ki =2.7 μm and 5.2 μm, respectively).akt is a serine/threonine-specific protein kinase that plays a vital role in multiple cellular processes including glucose metabolism, apoptosis, cell proliferation, transcription and cell migration etc.in bxpc-3 cells, pht-427 showed inhibition upon akt function with ic50 value of 8.6±0.8 μm and for its downstream substrates. pht-427 reduced the akt phosphorylation on ser473 residue and did not decrease total akt protein level. pht-427 also inhibited p70s6k and gsk3β in a dose-dependent manner. [1][2]in scid (severe combined immunodeficiency) mice of bxpc-3 pancreatic cancer xenografts, administration of pht-427 exerted prominent antitumor activity that halted tumor growth. pht-427 in combination with erlotinib exhibited greater than additive antitumor activity in nsc lung cancer and with paclitaxel in breast cancer.

This orally bioavailable, dual Akt/PDPK1 inhibitor (F.Wt. = 409.61; CAS 1191951-57-1 and 1178893-77-0; Solubility (25°C): 80 mg/mL DMSO, <1 mg/mL Water), known systematically as 4-dodecyl-N-(1,3,4-thiadiazol-2- yl)benzenesulfonamide, targets Akt (also known as Protein Kinase B, or PKB) and 3-phosphoinositide-dependent protein kinase-1, with Ki of 2.7 μM and 5.2 μM, respectively. PHT-427 was designed to bind to the pleckstrin homology (PH) auto-inhibitory domains of the signal cascade protein kinase Akt.
