Antibiotics

Rapamycin (Sirolimus; AY 22989) is a potent and specific blood-brain barrier-transmissible mTOR inhibitor with an IC₅₀ of 0.1 nM in HEK293 cells. Rapamycin is a molecular glue that binds FKBP12 and mTOR proteins together, thereby inhibiting mTOR kinase activity. Rapamycin binds to FKBP12 and specifically acts as an allosteric inhibitor of mTORC1. Rapamycin is an autophagy activator, an immunosuppressant.

Bafilomycin A1 (BafA1) is a specific and reversible inhibitor of vacuolar H⁺-ATPase (V-ATPase) with IC₅₀ values of 4-400 nmol/mg. Bafilomycin A1, a macrolide antibiotic, is also used as an autophagy inhibitor at the late stage. Bafilomycin A1 blocks autophagosome-lysosome fusion and inhibits acidification and protein degradation in lysosomes of cultured cells. Bafilomycin A1 induces apoptosis.

Brefeldin A (BFA) is a lactone antibiotic and a specific inhibitor of protein trafficking. Brefeldin A blocks the transport of secreted and membrane proteins from endoplasmic reticulum to Golgi apparatus. Brefeldin A is also an autophagy and mitophagy inhibitor. Brefeldin A inhibits HSV-1 and has anti-cancer activity.

Streptozotocin (Streptozocin; STZ) is an antibiotic widely used in experimental animal models of induced diabetes. Streptozotocin enters B cells via the glucose transporter (GLUT2) and causes the alkylation of DNA ( DNA-methylating ). Streptozotocin can induce the apoptosis of β cells.

Bleomycin sulfate is a DNA synthesis inhibitor. Bleomycin hydrochloride is a DNA damaging agent. Bleomycin sulfate is an antitumor antibiotic.

Concanamycin A (purity≥90%) (Antibiotic X 4357B) is a macrolide antibiotic, a vacuolar type H⁺-ATPase (V-ATPase) inhibitor. Concanamycin A (purity≥90%) is also an inhibitor of lysosomal acidification, can be used to T cell-mediated inflammation research^-.

Concanamycin A (purity≥70%) (Antibiotic X 4357B) is a macrolide antibiotic, a vacuolar type H⁺-ATPase (V-ATPase) inhibitor. Concanamycin A (purity≥70%) is also an inhibitor of lysosomal acidification, can be used to T cell-mediated inflammation research^-.

G-418 disulfate (Geneticin sulfate), is an aminoglycoside antibiotic, inhibits protein synthesis in eukaryotes and prokaryotes. G-418 disulfate is commonly used as a selective agent for eukaryotic cells.

Puromycin dihydrochloride (CL13900 dihydrochloride), an aminonucleoside antibiotic, inhibits protein synthesis.

Ionomycin (SQ23377) is a potent, selective calcium ionophore and an antibiotic produced by Streptomyces conglobatus. Ionomycin (SQ23377) is highly specific for divalent cations (Ca>Mg>Sr=Ba). Ionomycin (SQ23377) promotes apoptosis. Ionomycin also induces the activation of protein kinase C (PKC).

Hygromycin B is an aminoglycoside antibiotic active against prokaryotic and eukaryotic cells.

Tunicamycin is a mixture of homologous nucleoside antibiotic that inhibits N-linked glycosylation and blocks GlcNAc phosphotransferase (GPT). Tunicamycin causes accumulation of unfolded proteins in cell endoplasmic reticulum (ER) and induces ER stress, and causes blocking of DNA synthesis and cell cycle arrest in G1 phase. Tunicamycin inhibits gram-positive bacteria, yeasts, fungi, and viruses and has anti-cancer activity.Tunicamycin increases exosome release in cervical cancer cells.

Oligomycin, an antifungal antibiotic, is an inhibitor of H⁺-ATP-synthase. Oligomycin blocks oxidative phosphorylation and the electron transport chain. Oligomycin inhibits HIF-1alpha expression in hypoxic tumor cells.

Tacrolimus (FK506), a molecular glue, a macrocyclic lactone, binds to FK506 binding protein (FKBP) to form a complex. Tacrolimus inhibits calcineurin phosphatase, which inhibits T-lymphocyte signal transduction and IL-2 transcription. Immunosuppressive properties.

Neomycin sulfate, an aminoglycoside antibiotic, exerts antibacterial activity through irreversible binding of the nuclear 30S ribosomal subunit, thereby blocking bacterial protein synthesis. Neomycin sulfate is a known phospholipase C (PLC) inhibitor. Neomycin sulfate potently inhibits both the nuclear translocation of angiogenin and angiogenin-induced cell proliferation and angiogenesis. Neomycin sulfate inhibits IP3-mediated Ca²⁺ release, MgATP-dependent Ca²⁺ uptake, and electrical excitation-evoked skeletal muscle Ca²⁺ transients. Neomycin sulfate depletes gut microbiota in specific mouse models, causes hearing impairment, and kidney damage with prolonged exposure. Neomycin sulfate can be used for the research of cancer.

Nigericin sodium salt is an antibiotic derived from Streptomyces hygroscopicus that act as a K⁺/H⁺ ionophore, promoting K⁺/H⁺ exchange across mitochondrial membranes. Nigericin sodium salt is a NLRP3 activator. Nigericin sodium salt shows promising anti-cancer activities through decreasing intracellular pH (pHi), and inactivation of Wnt/β-catenin signals. Nigericin sodium salt induces pyroptosis through caspase 1/GSDMD in TNBC.

Anisomycin is a potent protein synthesis inhibitor which interferes with protein and DNA synthesis by inhibiting peptidyl transferase or the 80S ribosome system. Anisomycin is a JNK activator, which increases phospho-JNK. Anisomycin is a bacterial antibiotic.

Wortmannin (SL-2052; KY-12420) is a potent, selective and irreversible PI3K inhibitor with an IC₅₀ of 3 nM. Wortmannin also blocks autophagy formation, and potently inhibits Polo-like kinase 1 (PlK1) and Plk3 with IC₅₀s of 5.8 and 48 nM, respectively.

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