Sodium 4-phenylbutyrate (TriButyrate), a transcriptional regulator, reversibly inhibits class I and II histone deacetylases (HDACs )resulting in a global increase in gene expression, decreased cellular proliferation, increased cell differentiation, and the induction of apoptosis in susceptible tumor cell populations.

Gefitinib (ZD1839) is an EGFR first-generation inhibitor with oral activity that inhibits the EGFR 19 Del and L858R mutations. Gefitinib has antitumor activity and is used for the treatment of EGFR-mutated non-small-cell lung cancers. Gefitinib administration RESULTS in the development of the EGFR C797S resistance mutation.

Taurine (2-Aminoethanesulfonic acid) is an organic acid widely distributed in animal tissues and is one of the constituents of bile acids. Taurine is involved in a number of processes related to energy expenditure and muscle function, and can treat fatigue and muscles as well as improve immune function.

Curcumin (Natural Yellow 3) is a phenolic natural product, an inhibitor of histone acetyltransferase p300/CREB (IC50=25 μM) with specificity. Curcumin has a wide range of pharmacological activities such as antitumor, anti-inflammatory and antioxidant.

Metronidazole (Metronidazol) is a synthetic nitroimidazole derivative with antiprotozoal and antibacterial activities.

1. Oxyresveratro can inhibit tyrosinase activity. 2. Oxyresveratro is useful to trauma models, as toxicity to glia could be beneficial by inhibiting reactive gliosis. 3. Oxyresveratrol (trans-Oxyresveratrol) has antioxidant activity, can reduce neuronal oxidative damage and protect hepatocytes against oxidative stress and mitochondrial dysfunction, which may be associated with activation of Nrf2.

Xylitol (Ribitol) is a five-carbon sugar alcohol derived from XYLOSE by reduction of the carbonyl group. It is as sweet as sucrose and used as a noncariogenic sweetener.
