5-Fluorouracil (5-FU) is a uracil analog and inhibitor of DNA synthesis, exhibiting antitumor activity by affecting pyrimidine synthesis through thymidylate synthase inhibition; it induces apoptosis and autophagy.

Q-VD-OPh is an irreversible caspase inhibitor with an IC50 value of 48 nM against caspase-7 and between 25 and 400 nM against caspase-1, 3, 8, 9, 10, 12. Q-VD-OPh inhibits HIV infection and can cross the blood-brain barrier.

3-Deazaadenosine hydrochloride is an inhibitor of S-adenosylhomocysteine hydrolase (Ki: 3.9 µM). It has anti-inflammatory, anti-proliferative, and anti-HIV activity.

Flavopiridol (Alvocidib) (Alvocidib) competes with ATP to inhibit CDKs including CDK1, CDK2, CDK4 and CDK6 with IC50 of ~ 40 nM. It is 7.5-fold more selective for CDK1, 2, 4, 6 versus CDK7. Flavopiridol is initially found to inhibit EGFR and PKA. Phase 1/2.

Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that suppresses HDAC1 activity and induces HDAC2 degradation, exhibiting oral bioavailability. Valproic Acid activates Notch1 signalling and inhibits the proliferation of small cell lung carcinoma cells, making it applicable for research into epilepsy and bipolar disorder.

Chloroquine is a Toll-like receptor inhibitor that inhibits autophagy. Chloroquine has anti-malarial and anti-inflammatory activity and is widely used in the treatment of malaria and rheumatoid arthritis. Chloroquine also has anti-SARS-CoV-2 (COVID-19) activity and anti-HIV-1 activity.

Peldesine (BCX 34) is an effective, competitive, reversible, and orally active inhibitor of purine nucleoside phosphorylase. Peldesine inhibits T-cell proliferation with an IC50 of 800 nM. Peldesine can be used in research on cutaneous T-cell lymphoma, psoriasis and HIV infection.

ABBV-744 is a BDII-selective BET bromodomain inhibitor that inhibits BRD2/3/4. It is used in the research on inflammatory diseases, cancer, and AIDS.

5-(N,N-Hexamethylene)-amiloride (5-HMA) is an amiloride derivative that inhibits TRPA1-mediated calcium signaling (IC50: 35 μM). It functions as an inhibitor of the Na+/H+ exchanger (NHE) with Ki values ranging from 0.013 to 2.4 μM for various NHE isoforms. Additionally, 5-HMA blocks ASIC3 channels by 51% at 20 μM.

MK-2048 is a potent inhibitor of integrase (IN) and INR263K, with IC50 values of 2.6 nM and 1.5 nM, respectively.

Oxindole (Indolin-2-one) is an aromatic heterocyclic building block, and its 2-indolinone derivatives are lead compounds in kinase inhibitor research. The oxindole structure is utilized in receptor tyrosine kinase (RTK) inhibitors, such as SU4984 and intedanib, making the RTK family a significant therapeutic target for anti-cancer drug development.
