Several pyrrolo[2,3-b]pyridine-based B-RAF inhibitors are well known and some of them are currently FDA approved as anticancer agents. Based on the structure of these FDA approved V600EB-RAF inhibitors, two series of pyrrolo[2,3-b]pyridine scaffold were designed and synthesized in attempt to develop new potent V600EB-RAF inhibitors. The 38 synthesized compounds were biologically evaluated for their V600EB-RAF inhibitory effect at single dose (10 μM). Compounds with high percent inhibition were tested to determine their IC50 over V600EB-RAF. Compounds 34e and 35 showed the highest inhibitory effect with IC50 values of 0.085 μM and 0.080 μM, respectively. Headed for excessive biological evaluation, the synthesized derivatives were tested over sixty diverse human cancer cell lines. Only compound 35 emerged as a potent cytotoxic agent against different panel of human cancer cell lines.

The site of acylation in difunctional compounds containing an amine and either an amidine or guanidine can be determined from the ultraviolet absorption spectrum of the acylated product.If the amidine or guanidine has been acylated, the product possesses a chromophore that is pH dependent, whereas if an amide was formed, the chromophore is independent of pH.
