Small Molecule Inhibitors for Hepatocellular Carcinoma: Advances and Challenges

Abstract: According to data provided by World Health Organization, hepatocellular carcinoma (HCC) is the sixth most common cause of deaths due to cancer worldwide. Tremendous progress has been achieved over the last 10 years developing novel agents for HCC treatment, including small-molecule kinase inhibitors. Several small molecule inhibitors currently form the core of HCC treatment due to their versatility since they would be more easily absorbed and have higher oral bioavailability, thus easier to formulate and admin… Show more

“…Disrupting the PD-L1-mediated tumor immune escape by SMIs is more advantageous over monoclonal anti-bodies (mAbs). Despite their positive therapeutic efficacy, mAbs suffer from many limitations such as immune-related side effects (irAEs), complex production process, high treatment costs, and low permeability in the tumor tissues. On the other hand, SMIs have better oral bioavailability and tumor penetration, easier self-administration and have fewer side effects compared to mAbs, making immunomodulation by SMI an attractive approach for cancer treatment as reviewed . The increasing number of available crystal structures for PD-L1 bound to inhibitors helped in understanding the mechanism of inhibition of these compounds and paved the way for discovery of novel PD-L1 inhibitors. , …”

“…According to the data provided by the World Health Organization (WHO), hepatocellular carcinoma (HCC) is the world’s sixth most common malignant tumor and the third leading cause of cancer death worldwide in 2020 ( 1 ). It is characterized by a short duration of illness and is difficult to heal, and the invasion, metastasis, and spread of HCC cells are the reasons for the high mortality rate of this disease ( 2 ).…”

“…Sorafenib (NEXAVAR; SOR) is a multi-target protein kinase inhibitor approved for the treatment of hepatocellular carcinoma and advanced renal cell carcinoma [ 39 , 40 ]. Although SOR has not been approved for lung cancer, it is still the subject of extensive research related to lung cancer [ 41 , 42 , 43 ].…”
