Sorafenib induces cell cycle arrest, autophagy, apoptosis, and PARP cleavage, reduces Bcl-2, Bcl-XL, cyclin D1 levels, and activates Bak and Bax. Sorafenib inhibits tumor growth and metastasis in mouse and rat models. Sorafenib can be used for cancer research, such as colon, breast, non-small-cell lung cancer (NSCLC), ovarian, pancreatic, melanoma, colorectal and hepatocellular carcinoma.

5-Fluorouracil (5-FU) is an analogue of uracil and a potent antitumor agent. 5-Fluorouracil affects pyrimidine synthesis by inhibiting thymidylate synthetase thus depleting intracellular dTTP pools. 5-Fluorouracil induces apoptosis and can be used as a chemical sensitizer. 5-Fluorouracil also inhibits HIV.

Bortezomib (PS-341) is a reversible and selective proteasome inhibitor, and potently inhibits 20S proteasome (K_i=0.6 nM) by targeting a threonine residue. Bortezomib disrupts the cell cycle, induces apoptosis, and inhibits NF-κB. Bortezomib is the first proteasome inhibitor anticancer agent. Bortezomib can be used for the study of multiple myeloma (MM). Bortezomib effectively inhibits TREM2 expression in tumor-associated macrophages (TAMs).

Palbociclib (PD 0332991) is an orally active selective CDK4 and CDK6 inhibitor with IC₅₀ values of 11 and 16 nM, respectively. Palbociclib has potent anti-proliferative activity and induces cell cycle arrest in cancer cells, which can be used in the research of HR-positive and HER2-negative breast cancer and hepatocellular carcinoma.

Metformin (1,1-Dimethylbiguanide) inhibits the mitochondrial respiratory chain in the liver, leading to AMPK activation and enhancing insulin sensitivity, and can be used in the study of type 2 diabetes. Metformin exerts central glucose-lowering effects by inhibiting Ras-related protein 1 (Rap1) in SF1 hypothalamic neurons. Metformin also inhibits liver oxidative stress, nitrosative stress, inflammation, and apoptosis caused by liver ischemia/reperfusion injury. In addition, Metformin regulates the expression of autophagy-related proteins by activating AMPK and inhibiting the mTOR signaling pathway, thereby inducing tumor cell autophagy and inhibiting the growth of renal cell carcinoma in vitro and in vivo.
