Oxidopamine (6-OHDA) hydrobromide is an antagonist of the neurotransmitter dopamine. Oxidopamine hydrobromide is a widely used neurotoxin and selectively destroys dopaminergic neurons. Oxidopamine hydrobromide promotes COX-2 activation, leading to PGE₂ synthesis and pro-inflammatory cytokine IL-1β secretion. Oxidopamine hydrobromide can be used for the research of Parkinson’s disease (PD), attention-deficit hyperactivity disorder (ADHD), and Lesch-Nyhan syndrome.

Fludarabine (NSC 118218) is a DNA synthesis inhibitor and a fluorinated purine analogue with antineoplastic activity in lymphoproliferative malignancies. Fludarabine inhibits the cytokine-induced activation of STAT1 and STAT1-dependent gene transcription in normal resting or activated lymphocytes.

(-)-Epigallocatechin Gallate (EGCG) is a major polyphenol in green tea, which can inhibit cell proliferation and induce cell apoptosis. (-)-Epigallocatechin Gallate inhibits glutamate dehydrogenase 1/2 (GDH1/2, GLUD1/2) activity. (-)-Epigallocatechin Gallate has a potent anticancer, antioxidant and anti-inflammatory properties against various types of cancers such as colorectal cancer, myeloid leukemia, thyroid carcinoma.

Camptothecin (CPT), a kind of alkaloid, is a DNA topoisomerase I (Topo I) inhibitor with an IC₅₀ of 679 nM. Camptothecin (CPT) exhibits powerful antineoplastic activity against colorectal, breast, lung and ovarian cancers, modulates hypoxia-inducible factor-1α (HIF-1α) activity by changing microRNAs (miRNA) expression patterns in human cancer cells.

Metronidazole is an orally active nitroimidazole antibiotic. Metronidazole can cross blood brain barrier. Metronidazole can be used for the research of anaerobic infections.

Sulforaphane is an orally active inducer of the Keap1/Nrf2/ARE pathway. Sulforaphane promotes the transcription of tumor-suppressing proteins and effectively inhibits the activity of HDACs. Through the activation of the Keap1/Nrf2/ARE pathway and further induction of HO-1 expression, Sulforaphane protects the heart. Sulforaphane suppresses high glucose-induced pancreatic cancer through AMPK-dependent signal transmission. Sulforaphane exhibits both anticancer and anti-inflammatory properties.

Ro-3306 is a potent and selective inhibitor of CDK1, with K_is of 20 nM, 35 nM and 340 nM for CDK1, CDK1/cyclin B1 and CDK2/cyclin E, respectively.

Exendin‑4 (Exenatide) is an orally active, blood-brain barrier-permeable glucagon-like peptide-1 receptor (GLP‑1 receptor) agonist that resists degradation mediated by dipeptidyl peptidase IV. Exendin‑4 mediates multiple glucose-regulating effects, including stimulation of glucose-dependent insulin secretion, inhibition of glucagon production, increase in β-cell mass, delay of gastric emptying, reduction of food intake, improvement of peripheral insulin sensitivity, and restoration of normal islet structure. Exendin‑4 inhibits oxidative stress, alleviates inflammatory responses, and reduces neuronal apoptosis. Exendin‑4 reduces the aggregation level of mutant huntingtin, improves motor function, prolongs survival time, and regulates the expression levels of leptin and ghrelin. Exendin‑4 can be used in research related to type 2 diabetes, acute ischemic stroke, and Huntington's disease.

Trolox is an analogue of vitamin E with a powerful antioxidant effect. Trolox is also a powerful inhibitor of membrane damage.

TAK-243 (MLN7243) is a first-in-class, selective ubiquitin activating enzyme, UAE (UBA1) inhibitor (IC₅₀=1 nM), which blocks ubiquitin conjugation, disrupting monoubiquitin signaling as well as global protein ubiquitination. TAK-243 (MLN7243) induces endoplasmic reticulum (ER) stress, abrogates NF-κB pathway activation and promotes apoptosis.

C646 is a selective and competitive histone acetyltransferase p300 inhibitor with K_i of 400 nM, and is less potent for other acetyltransferases.

Luteolin (Luteoline), a flavanoid compound, is a potent Nrf2 inhibitor. Luteolin has anti-inflammatory, anti-cancer properties, including the induction of apoptosis and cell cycle arrest, and the inhibition of metastasis and angiogenesis, in several cancer cell lines, including human non-small lung cancer cells.

Afatinib (BIBW 2992) is an orally active, potent and irreversible dual specificity inhibitor of ErbB family (EGFR and HER2), with IC₅₀ values of 0.5 nM, 0.4 nM, 10 nM and 14 nM for EGFR^wt, EGFR^L858R, EGFR^L858R/T790M and HER2, respectively. Afatinib can be used for the research of esophageal squamous cell carcinoma (ESCC), non-small cell lung cancer (NSCLC) and gastric cancer.

Atezolizumab (MPDL3280A) is a selective humanized monoclonal IgG1 antibody against programmed death ligand 1 (PD-L1), used for cancer research.

L-Glutamic acid is an excitatory amino acid neurotransmitter that acts as an agonist for all subtypes of glutamate receptors (metabolic rhodophylline, NMDA, and AMPA). L-Glutamic acid has an agonist effect on the release of DA from dopaminergic nerve endings. L-Glutamic acid can be used in the study of neurological diseases. L-Glutamic acid acts at ionotropic and metabotropic glutamate receptors.
