Small-Molecule Inhibitors of Protein Geranylgeranyltransferase Type I
摘要:
Small molecules that inhibit the geranylgeranylation of K-Ras4B and RhoA by protein geranylgeranyltransferase type I (GGTase-I) were identified from chemical genetic screens of heterocycles synthesized through phosphine catalysis of allenes. To further improve the efficacy of the GGTase-I inhibitors (GGTIs), 4288 related compounds bearing core dihydropyrrole/pyrrolidine and tetrahydropyridine/piperidine scaffolds were synthesized on SynPhase lanterns in a split-pool manner through phosphine-catalyzed [3 + 2] and [4 + 2] annulations of resin-bound allenoates. Testing of the 4288 analogues resulted in several GGTIs exhibiting submicromolar IC50 values. Because proteins such as Ras and Rho GTPases are implicated in oncogenesis and metastasis, these GGTIs might ultimately lead to the development of novel antitumor therapeutics.
The present invention is directed to novel compounds. These compounds can be useful in inhibiting the activity of protein prenyltransferases including GGTase I and/or RabGGTase. The compounds can also be used as anti-cancer therapeutics including as part of methods for treating cancer, in assays, and in kits.
