A facile and improved route for the synthesis of the orally active spiroindoline-based growth hormone secretagogue, MK-677 was described. The key step adopted the Fischer indole/reduction strategy. The preparation of the key intermediates N-protected piperidine carboxaldehyde 5 and the N-Boc-O-benzyl-d-serine (2) are also optimized.

The multiple roles of protein kinase D (PKD) in various cancer hallmarks have been repeatedly reported. Therefore, the search for novel PKD inhibitors and their evaluation as antitumor agents has gained considerable attention. In this work, novel pyrazolo[3,4-d]pyrimidine based pan-PKD inhibitors with structural variety at position 1 were synthesized and evaluated for biological activity. Starting from 3-IN-PP1, a known PKD inhibitor with IC50 values in the range of 94–108 nM, compound 17m was identified with an improved biochemical inhibitory activity against PKD (IC50 = 17–35 nM). Subsequent cellular assays demonstrated that 3-IN-PP1 and 17m inhibited PKD-dependent cortactin phosphorylation. Furthermore, 3-IN-PP1 displayed potent anti-proliferative activity against PANC-1 cells. Finally, a screening against different cancer cell lines demonstrated that 3-IN-PP1 is a potent and versatile antitumoral agent.
