Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that inhibits HDAC1 activity, induces HDAC2 degradation, and is orally active. Valproic Acid can be used in epilepsy and bipolar disorder research.

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.

Naringin (Naringoside), a flavanone glycoside, exerts various of pharmacological effects such as blood lipid lowering, antioxidant activity, anticancer activity, and inhibition of cytochrome P450 enzymes.

Guanidine hydrochloride (Aminoformamidine Hydrochloride) is a strong organic base existing primarily as guanidium ions at physiological pH. It is found in the urine as a normal product of protein metabolism. It is also used in laboratory research as a protein denaturant.

L-Cystine (Cystine Acid) is not considered one of the 20 amino acids, L-Cystine (Cystine Acid) is a sulfur-containing derivative obtained from oxidation of cysteine amino acid thiol side chains. It functions as an antioxidant and protects tissues against radiation and pollution, slowing the aging process. It also aids protein synthesis. L-Cystine (Cystine Acid) is abundant in many proteins of skeletal tissues and skin, and found in insulin and digestive enzymes chromotrypsinogen A, papain, and trypsinogen.

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.

Hydroxychloroquine (2-[[4-[(7-Chloroquinolin-4-yl)amino]pentyl](ethyl)amino]ethanol) (HCQ) is an alkalinizing lysosomatropic drug that acts by inducing apoptosis of renal cancer cells in vitro and inhibiting TLR7/9. It is a medication used to prevent and treat malaria, and it's also being studied as an experimental treatment for COVID-19.

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.
