Abstract

Ugi reaction was a reliable procedure for the synthesis of new coumarin-quinoline frameworks. Excellent yields, mild reaction conditions and easily available and inexpensive starting materials are advantages of this protocol. Cytotoxic effects of fourteen products were investigated in A2780 human ovarian cancer cells. Two synthesized compounds (L11 and L12) exhibited more anti-cancer activity than other derivatives with IC50 values of 0.042 mmol/L and 0.102 mmol/L, respectively and were thus selected for further studies. Apoptosis was induced through the intrinsic pathway by activating caspase 9 and ended at the executioner pathway of caspase 3. Measurement of intracellular reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) were also carried out for both of them. Further studies on a mechanism by Real Time-PCR and Western blot analysis were performed for anti-apoptotic proteins Bcl-2 and survivin both in mRNA and protein level relating to the untreated A2780 cells. The treatment of A2780 cells with compound L11 significantly (P-value ≤ 0.05) induced apoptosis by down-regulation of Bcl-2 and survivin both in mRNA and protein level via a single dose (0.042 mmol/L), as well as activation of caspase 9 and 3, l...Continue Reading

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
