Synthesis and Antitumor Evaluation of Some New Derivatives and Fused Heterocyclic Compounds Derived from Thieno[2,3- b]pyridine: Current Perspective | Chapter 2 | Current Research and Development in Chemistry Vol. 3


On the basis of the proven activity of thieno[2,3-b]pyridines as anticancer, we have designed to
synthesize a novel several heterocyclic compounds utilizing thieno[2,3-
b]pyridine as a skeleton
through various chemical reactions. The synthesized compounds bear rings that are either directly
attached to the thieno[2,3-
b]pyridine as in compounds 4 to 6 and 9 or connected through an amide
bridge as compounds
2, 3a-b, 7, and 8. As well as, compounds 10, 12 to 28, 30, 31, and 33 to 36
bear fused rings to the thieno[2,3-b]pyridine back-bone. The newly synthesized compounds were
screened for their antiproliferative activity
in vitro against hepatocellular carcinoma (HepG-2) and
breast cancer (MCF-7) compared with the standard drug (doxorubicin). Compounds
3b, 4, 6, 22, and
28 exhibited promising growth inhibitory effect toward both HepG-2 and MCF-7 cell lines with IC50
values ranging from 5.88 to 11.70 μg/ mL and 9.64 to 15.10 μg/mL, respectively.
