PHT-7.3 is a selective inhibitor of connector enhancer of kinase suppressor of Ras 1 (Cnk1) pleckstrin homology (PH) domain (K_d=4.7 μM). PHT-7.3 inhibits mut-KRas, but not wild-type KRas cancer cell and tumor growth and signaling. PHT-7.3 has antitumor activity^[1].

Cnk1 PH-domain^[1]

PHT-7.3 (200 mg/kg; i.p.; daily; for 20 days) exhibits cytostatic antitumor activity in the mut-KRas(G12S) A549 xenograft and mut-KRasG12V H441 xenograft^[1].

PHT-247 is an inhibitor of the pleckstrin homology (PH) domain of Akt, and it is also an inhibitor of PDPK1 with K_is of 2.7 µM and 5.2 µM and for Akt and PDPK1, respectively.

The effects of PHT-427 on cell signaling are investigated by RPPA using a panel of 86 antibodies to phospho- and non-phosphorylated signaling protein related to PtdIns-3-K/PDPK1/Akt signaling in PC-3 prostate cells where PtdIns-3-K/PDPK1/Akt signaling is activated because of homozygous PTEN mutation. After 16 hours, a reduction is observed in phospho-Ser²⁴¹-PDPK1 phospho-Thr³⁰⁸-Akt by both 10 µM PH-427 and 0.1 µM Wortmannin. Finally, phospho-Ser⁶⁵⁷-protein kinase C (PKC) and total SGK1 are decreased by treatment with both PHT-427 and Wortmannin. These results suggest that at 10 µM PHT-427 inhibits both Akt and PDKP1. The BxPC-3 and MiaPaCa-2 pancreatic cancer cell lines are probed by Western blotting following up to 24 hr exposure to 10 µM PHT-427, which is below the IC₅₀ for cell growth inhibition of around 30 µM, to determine the effects of PHT-427 on of the PtdIns-3-K/PDPK1/Akt signaling pathway components^[1].

Mice with BxPC-3 pancreatic, MCF-7 breast or A-549 NSCL cancer xenografts are administered PHT-427, or its analogs with a C-4, C-6 or C-8 alkyl chain by oral gavage twice a day for 10 days. The results show that PHT-427 has the greatest antitumor activity with the C-8 chain analog having less activity, and analogs with a C-4 or C-6 chain very little activity. All further antitumor studies are conducted using compound PHT-427. Plasma levels of PHT-427 following oral administration to mice of a dose of 200 mg/kg show rapid absorption, without a lag phase, C_max is 8.2 µg/mL 1 hr following dosing, and the elimination half-life is 1.4 hr with a terminal PHT-427 concentration of 0.1 µg/mL 10 hr after dosing. The plasma concentration of PH-427 is above the level which gave inhibition of Akt and PDPK1 signaling in cells of 10 µM (4 µg/mL) for at least 3 hr^[1].

Panc-1 cells stably transfected with green fluorescent protein (GFP) tagged Akt or PDKP1 PH domains are serum starved in phenol red free growth medium on glass-bottom 96-well imaging plates for 16 hours. They are then treated with PHT-427 at 1, 5, and 10 µM or PI-103 for 4 hr, and stimulated with 50 ng/mL IGF-1 for 10 min. Images are taken before and after IGF-1 treatment using an IN Cell Analyzer 1000 instrument with a Nikon Plan Fluor ELWD 20X/0.45 objective loaded and using a 300msec exposure time^[1].

Mice^[1]
Female C57Bl/6 mice are administered PHT-427 as a single oral dose of 200 mg/kg. The mice are killed at different times (3 mice at each time point), blood collected into heparinized tubes and plasma prepared and stored frozen at -80°C. For assay 0.2 mL plasma is mixed with 0.2 mL of 0.1 M sodium phosphate buffer, pH 4.0, and extracted for 1 hr by inversion with 1 ml ethyl acetate. After centrifugation 0.8 mL of the organic layer is removed, evaporated under N₂ and redissolved in 0.2 mL ethanol and 10 µL injected onto a Waters Quattro Ultima tandem mass spectrometer using a Phenomenex Luna 3.0 µm, 2.0×50 mm C8 analytical column with detection and quantification by multiple reaction monitoring with the mass spectrometer operating in electrospray positive ionization mode.
