Signaling pathways intersecting with the p21-activated kinases (PAKs) play important roles in tumorigenesis and cancer progression. By recognizing that the limitations of FRAX1036 (1) were chiefly associated with the highly basic amine it contained, we devised a mitigation strategy to address several issues such as hERG activity. The 5-amino-1,3-dioxanyl moiety was identified as an effective means of reducing pKa and logP simultaneously. When positioned properly within the scaffold, this group conferred several benefits including potency, pharmacokinetics, and selectivity. Mouse xenograft PK/PD studies were carried out using an advanced compound, G-5555 (12), derived from this approach. These studies concluded that dose-dependent pathway modulation was achievable and paves the way for further in vivo investigations of PAK1 function in cancer and other diseases.

Paragraph 0007, (2021/01/11)
The invention relates to a synthetic route of a generic FGFR covalent inhibitor PRN1371, and belongs to the field of medicinal chemistry. The synthetic route steps of the PRN1371 comprise 11 steps, purification of a product can be achieved through simple operation of various intermediates in the aftertreatment process, the problems that the product is difficult to separate, the purification operation yield is low and the like are solved, and industrial production is facilitated. The invention aims to provide a synthetic route of the FGFR irreversible covalent inhibitor PRN1371, and the methodhas the advantages of few synthesis steps, simple operation, high yield, reduction of the production cost, and provision of a new synthesis idea for the industrial production of PRN1371.
