We synthesized five novel tryptamine derivatives characterized by the presence of an azelayl chain or of a 1,1,1-trichloroethyl group, in turn connected to another heterocyclic scaffold. The combination of tryptamin-, 1,1,1-trichloroethyl- and 2-aminopyrimidinyl- moieties produced compound 9 identified as the most active compound in hematological cancer cell lines (IC50 = 0.57–65.32 μM). Moreover, keeping constant the presence of the tryptaminic scaffold and binding it to the azelayl moiety, the compounds maintain biological activity. Compound 13 is still active against hematological cancer cell lines and shows a selective effect only on HT29 cells (IC50 = 0.006 µM) among solid tumor models. Compound 14 loses activity on all leukemic lines, while showing a high level of toxicity on all solid tumor lines tested (IC50 0.0015–0.469 µM).

End Products

Gastrin-releasing peptide (GRP) has a widespread distribution and multiple stimulating effects on endocrine and exocrine secretions and metabolism. The prohormone for GRP (ProGRP, 125 amino acids) is processed to the amidated, biologically active end products GRP1–27 and GRP18–27. Amidated forms of GRP are putative autocrine or paracrine growth factors in a number of cancers including colorectal cancer. However, the potential role and biological activity of proGRP has not been investigated. Using a newly developed antisera directed to the N terminus of human proGRP, proGRP immunoreactivity was detected in all of the endometrial, prostate, and colon cancer cell lines tested and in nine of 10 resected colorectal carcinomas. However, no amidated forms were detected, suggesting an attenuation of processing in tumors. Recombinant proGRP was expressed as a His-tag fusion protein and purified by metal affinity chromatography and HPLC. ProGRP stimulated proliferation of a colon cancer cell line and activated MAPK, but unlike GRP18–27amide had no effect on inositol phosphate production. ProGRP did not compete with iodinated bombesin in binding assays on Balb-3T3 cells transfected with the known GRP receptors, GRP-R or BRS-3. We conclude that proGRP is present in a number of cancer cell lines and in resected colorectal tumors and is biologically active. Our results suggest that antagonists to GRP precursors rather than the amidated end products should be developed as a treatment for colorectal and other cancers that express proGRP-derived peptides.

The small GTPase KRAS, which is frequently mutated in human cancers, must be localized to the plasma membrane (PM) for biological activity. We recently showed that the KRAS C-terminal membrane anchor exhibits exquisite lipid-binding specificity for select species of phosphatidylserine (PtdSer). We, therefore, investigated whether reducing PM PtdSer content is sufficient to abrogate KRAS oncogenesis. Oxysterol-related binding proteins ORP5 and ORP8 exchange PtdSer synthesized in the ER for phosphatidyl-4-phosphate synthesized in the PM. We show that depletion of ORP5 or ORP8 reduced PM PtdSer levels, resulting in extensive mislocalization of KRAS from the PM. Concordantly, ORP5 or ORP8 depletion significantly reduced proliferation and anchorage-independent growth of multiple KRAS-dependent cancer cell lines, and attenuated KRAS signaling in vivo. Similarly, functionally inhibiting ORP5 and ORP8 by inhibiting PI4KIIIα-mediated synthesis of phosphatidyl-4-phosphate at the PM selectively inhibited the growth of KRAS-dependent cancer cell lines over normal cells. Inhibiting KRAS function through regulating PM lipid PtdSer content may represent a viable strategy for KRAS-driven cancers.
