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.

AZD-7648 is a potent, orally active, selective DNA-PK inhibitor with an IC₅₀ of 0.6 nM. AZD-7648 induces apoptosis and shows antitumor activity.

PR-619 is a broad-range and reversible DUB inhibitor with EC₅₀s of 3.93, 4.9, 6.86, 7.2, and 8.61 μM for USP4, USP8, USP7, USP2, and USP5, respectively. PR-619 induces ER Stress and ER-Stress related apoptosis.

Entinostat is an oral and selective class I HDAC inhibitor, with IC₅₀s of 243 nM, 453 nM, and 248 nM for HDAC1, HDAC2, and HDAC3, respectively.

Sunitinib (SU 11248) is a multi-targeted receptor tyrosine kinase inhibitor with IC₅₀s of 80 nM and 2 nM for VEGFR2 and PDGFRβ, respectively. Sunitinib, an ATP-competitive inhibitor, effectively inhibits autophosphorylation of Ire1α by inhibiting autophosphorylation and consequent RNase activation.

Adenosine (Adenine riboside), a ubiquitous and BBB-permeable endogenous autacoid, acts through the enrollment of four G protein-coupled receptors: A1, A2A, A2B, and A3. Adenosine affects almost all aspects of cellular physiology, including neuronal activity, vascular function, platelet aggregation, and blood cell regulation.

Urolithin A, a gut-microbial metabolite of ellagic acid, exerts anti-inflammatory, antiproliferative, and antioxidant properties. Urolithin A induces autophagy and apoptosis, suppresses cell cycle progression, and inhibits DNA synthesis.

Carfilzomib (PR-171) is an irreversible proteasome inhibitor with an IC₅₀ of 5 nM in ANBL-6 and RPMI 8226 cells.

Pomalidomide, the third-generation immunomodulatory agent, acts as molecular glue. Pomalidomide interacts with the E3 ligase cereblon and induces degradation of essential Ikaros transcription factors.

Daporinad (FK866) is a non-competitive inhibitor of nicotinamide phosphoribosyltransferase (Nampt), with a K_i value of 0.3 nM. Daporinad depletes NAD+ and ATP levels, inhibits mTORC1 and MAPK/ERK pathways, and activates TFEB to induce autophagy. Daporinad causes the depletion of the endoplasmic reticulum Ca²⁺ pool, ultimately weakening the mitogen-induced Ca²⁺ signal and the activation and function of T cells. Daporinad induces cell cycle arrest and apoptosis, and inhibits cell proliferation. Daporinad can be used for the study of myeloma, liver cancer, and immunosuppression.

Niraparib (MK-4827) is a highly potent and orally bioavailable PARP1 and PARP2 inhibitor with IC₅₀s of 3.8 and 2.1 nM, respectively. Niraparib leads to inhibition of repair of DNA damage, activates apoptosis and shows anti-tumor activity.

Panobinostat (LBH589; NVP-LBH589) is a potent and orally active non-selective HDAC inhibitor, and has antineoplastic activities. Panobinostat induces HIV-1 virus production even at low concentration range 8-31 nM, stimulates HIV-1 expression in latently infected cells. Panobinostat induces cell apoptosis and autophagy. Panobinostat can be used for the study of refractory or relapsed multiple myeloma.

Sodium dichloroacetate is an orally active pyruvate dehydrogenase kinase (PDK) inhibitor. Sodium dichloroacetate also stimulates pyruvate dehydrogenase (PDH) activity and works as a Na⁺-K⁺-2Cl⁻ cotransporter (NKCC) inhibitor. Sodium dichloroacetate prevents the phosphorylation of the E1α subunit of PDC, promoting the entry of pyruvate into the mitochondria for oxidative metabolism, reducing lactate production, and simultaneously increasing the production of reactive oxygen species (ROS). Sodium dichloroacetate inhibits tumor cell proliferation and induces apoptosis. Sodium dichloroacetate is promising for research of cancers.

Nutlin-3a (Rebemadlin), an active enantiomer of Nutlin-3, is a potent murine double minute (MDM2) inhibitor (IC₅₀=90 nM). Nutlin-3a inhibits MDM2-p53 interactions and stabilizes the p53 protein, and induces cell autophagy and apoptosis. Nutlin-3a has the potential for the study of TP53 wild-type ovarian carcinomas.

Lenalidomide (CC-5013), a derivative of Thalidomide, acts as molecular glue. Lenalidomide is an orally active immunomodulator. Lenalidomide (CC-5013) is a ligand of ubiquitin E3 ligase cereblon (CRBN), and it causes selective ubiquitination and degradation of two lymphoid transcription factors, IKZF1 and IKZF3, by the CRBN-CRL4 ubiquitin ligase. Lenalidomide (CC-5013) specifically inhibits growth of mature B-cell lymphomas, including multiple myeloma, and induces IL-2 release from T cells.

Kaempferol (Kempferol), a flavonoid found in many edible plants, inhibits estrogen receptor α expression in breast cancer cells and induces apoptosis in glioblastoma cells and lung cancer cells by activation of MEK-MAPK. Kaempferol can be uesd for the research of breast cancer.

Hydroxyurea is a cell apoptosis inducer that inhibit DNA synthesis through inhibition of ribonucleotide reductase. Hydroxyurea shows anti-orthopoxvirus activity.

Pitstop 2 is a clathrin inhibitor which inhibits clathrin-mediated endocytosis (CME) by associating with the terminal domain of clathrin. Pitstop 2 has the potential for anti-cancer research.
