Abstract
The microbial polyketide, 2, 4-diacetylphloroglucinol (DAPG), exhibited a broad-spectrum of anti-leukemic, anti-lung, and anti-breast cancer properties. The aim of the present investigation was to study the interactive potentials of DAPG with the metastatic proteins such as MMP-2, MMP-9, and NF-κB and antiapoptotic Bcl-2 family proteins such as Bcl-2, Bcl-w, and Bcl-xL through in silico interaction and in vitro studies. The in silico modeling predicted high interactions of DAPG with the metastatic proteins, especially MMP-2, MMP-9, and NF-κB with the glide score of -7.028, -6.304, and -5.231, respectively. Similarly, the DAPG had weak interactions with the antiapoptotic Bcl-2, Bcl-w, and Bcl-xL with the glide score of -4.505, -3.839, and -4.003, respectively. The interaction studies further revealed the inhibition of MMP-2, MMP-9, and NF-κB activities with the low IC50 concentration of 5.82 ± 1.6, 6.74 ± 1.2, and 10.7 ± 1.5 μM respectively, in the presence of DAPG. Similarly, DAPG inhibited the Bcl-2, Bcl-xL and Bcl-w activities with the high IC50 concentration of 29.8 ± 1.9, 85.9 ± 2.7, and 97.4 ± 1.5 μM, respectively. These results correlate with the relatively high IC50 concentration of 16.3 ± 1.76, 7.67 ± 0.78, and 10.7 ± 0...Continue Reading
