- Liver pyruvate kinase (PKL) is a key player in controlling metabolic pathways and ATP production within the liver's glycolysis pathway. Since PKL modulators have been identified as a promising target for treating hepatocellular carcinoma (HCC) and non-alcoholic fatty liver disease (NAFLD), our research is centered on the development and synthesis of derivatives of N-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl) naphthalene-1-sulfonamide with the aim of modulating PLK. To improve PKL specificity, we used structural analysis and modeling as a guide. Notably, compound PKL-05 became the series' only active ingredient. DFT, Hirshfeld surface analysis, and molecular docking were used in our study to thoroughly examine the connection between compound structures and their computational functions. The global hardness and softness energy values, as well as the HOMO-LUMO energy gap value, were computed in order to forecast the chemical reactivity of this newly synthesized molecule. These energy values indicate that this molecule tends to be chemically stable and has little chemical reactivity. The results demonstrated a strong agreement between theoretical forecasts and experimental findings. In particular, PKL-05 exhibits encouraging traits that establish it as a useful starting point for additional research in the search for innovative PKL modulators to tackle the treatment issues associated with NAFLD and HCC.

- Non-alcoholic fatty liver disease (NAFLD) comprises a broad range of liver disease including hepatocellular carcinoma (HCC) with is no FDA-approved drug. Liver pyruvate kinase (PKL) is a major regulator of metabolic flux and ATP generation in liver presenting a potential target for the treatment of NAFLD. Based on our recent finding of JNK-5A's effectiveness in inhibiting PKLR expression through a drug repositioning pipeline, this study aims to improve its efficacy further. We synthesized a series of JNK-5A analogues with targeted modifications, guided by molecular docking studies. These compounds were evaluated for their activities on PKL expression, cell viability, triacylglyceride (TAG) levels, and the expressions of steatosis-related proteins in the human HepG2 cell line. Subsequently, the efficacy of these compounds was assessed in reducing TAG level and toxicity. Compounds 40 (SET-151) and 41 (SET-152) proved to be the most efficient in reducing TAG levels (11.51 ± 0.90 % and 10.77 ± 0.67 %) and demonstrated lower toxicity (61.60 ± 5.00 % and 43.87 ± 1.42 %) in HepG2 cells. Additionally, all synthesized compounds were evaluated for their anti-cancer properties revealing that compound 74 (SET-171) exhibited the highest toxicity in cell viability with IC50 values of 8.82 µM and 2.97 µM in HepG2 and Huh7 cell lines, respectively. To summarize, compounds 40 (SET-151) and 41 (SET-152) show potential for treating NAFLD, while compound 74 (SET-171) holds potential for HCC therapy.
