Theliatinib, also known as HMPL-309, is a novel small molecule, epidermal growth factor receptor tyrosine kinase inhibitor with potential antineoplastic and anti-angiogenesis activities. In vitro studies suggest that Theliatinib is a potent EGFR kinase inhibitor with good kinase selectivity and in vivo data demonstrated broad spectrum anti-tumor activity via oral dosing in multiple xerographs such as A-431, Bcap-37 and Fadu.

(3aR,6aR)-N-(4-(3-ethynylphenylamino)-7-methoxyquinazolin-6-yl)-l-methyl-hexahydropyrrolo [3,4-b]pyrrole-5(lH)-carboxamide

[060] To a solution of Compound 3-a (40 g, 0.138 mol, prepared according to procedures disclosed in WO2010002845), pyridine (40 mL, 0.495 mol) and DMF (anhydrous, 22 mL) in anhydrous THF (500 mL), was added phenyl carbonochloridate 3-b (22 mL, 0.175 mol) dropwise at -10°C. The mixture was stirred at room temperature for 12 hours. The precipitates were filtered and then suspended in saturated NaHC0₃ solution (500 mL). The solid was filtered, washed with H₂0 and EtOAc, and dried in vacuum to give compound 3-c (46 g).

A mixture of compound 3-c (1 g, 2.44 mmol) and compound 3-d (369 mg, 2.92 mmol) in dioxane (30mL) was stirred at 70°C for 5 hours, and then cooled to the ambient temperature. The precipitates were filtered, washed with EtOAc, and dried in vacuum to give compound 3 (0.8 g). MS (m/e): 443.4 (M+l)⁺.

Theliatinib (HMPL-309)

Theliatinib (HMPL-309) is a novel small molecule, epidermal growth factor receptor tyrosine kinase inhibitor with potential antineoplastic and anti-angiogenesis activities. Theliatinib is being developed as an oral formulation for the treatment of solid tumors like non-small cell lung cancer.

Theliatinib pre-clinical studies were conducted in China. In vitro studies suggest that Theliatinib is a potent EGFR kinase inhibitor with good kinase selectivity and in vivo data demonstrated broad spectrum anti-tumor activity via oral dosing in multiple xerographs such as A-431, Bcap-37 and Fadu. Non-clinical safety studies have indicated that Theliatinib is generally well tolerated in animals.

In November 2012, HMP initiated the first-in-human clinical trials of theliatinib.
