Activators & Inhibitors

TPU-0037C (Legacy Tebubio ref. 282T37546). TPU-0037C is a metabolite of the marine actinomycete S. platensis that is structurally similar to lydicamycin . It is active against Gram-positive bacteria (MICs = 0.39-3.13 μg/ml), including methicillin-resistant S. aureus strains (MIC = 3.13 μg/ml), but is ineffective against Gram-negative bacteria (MICs = >50 μg/ml).

trans-Urocanic Acid (Legacy Tebubio ref. 282T37547). trans-Urocanic Acid ((E)-Urocanic acid), a compound predominantly distributed in the hippocampus and prefrontal cortex, is an isomer of cis-UCA, an epidermal UV-protectant, which enhances the stability of tenofovir eplerenomide in long-acting HIV applications. trans-Urocanic acid potently modulates immune trans-urocanic acid effectively modulates immune function, inhibits human natural killer cell activity in vitro, and can be used in Alzheimer's disease research.

azido-FTY720 (Legacy Tebubio ref. 282T37548). FTY720 is a derivative of ISP-1 (myriocin), a fungal metabolite of the Chinese herb Iscaria sinclarii as well as a structural analog of sphingosine. It is a novel immune modulator that prolongs allograft transplant survival in numerous models by inhibiting lymphocyte emigration from lymphoid organs. FTY720 is phosphorylated by sphingosine kinase, which then acts as a potent agonist at four of the sphingosine-1-phosphate (S1P) receptors (S1P1, S1P3, S1P4, and S1P5). Down-regulation of S1P1 receptors on T and B lymphocytes by FTY720 results in defective egress of these cells from spleen, lymph nodes, and Peyer's patch. azido-FTY720 is a highly photoreactive analog of FTY720 that can be used to identify receptor binding sites for this ligand.

Bacillosporin C (Legacy Tebubio ref. 282T37549). Bacillosporin C is an oxaphenalenone dimer originally isolated from T. bacillosporus. This anhydride is formed from the lactone bacillosporin D in the mangrove endophytic fungus SBE-14. Similar oxaphenalenone dimers exhibit antibiotic activity and inhibit acetylcholinesterase.

Pinostilbene (Legacy Tebubio ref. 282T3755). Pinostilbene obviously attenuates the phosphorylation of c-Jun and JNK triggered by 6-OHDA.

Bacitracin Complex (Legacy Tebubio ref. 282T37550). Bacitracin complex is a bacitracin antibiotic complex composed of cyclic dipeptides that has been found inBacillus.1It is metal-dependent and is complexed to a divalent metal cation, such as Cu2+, Ni2+, Co2+, Zn2+, or Mn2+, for its activity.1,2Bacitracin complex is a mixture of bacitracin polypeptides in complex with copper.

(+)-D-threo-PDMP (hydrochloride) (Legacy Tebubio ref. 282T37551). (+)-D-threo-PDMP is a ceramide analog and is one of the four possible stereoisomers of PDMP . (+)-D-threo-PDMP is an inhibitor of glucosylceramide synthase. It inhibits glucosylceramide synthase by 50% when used at a concentration of 5 μM in an enzyme assay. (+)-D-threo-PDMP is the active component of racemic DL-threo-PDMP .

(+)-Macrosphelide A (Legacy Tebubio ref. 282T37552). (+)-Macrosphelide A is a fungal metabolite originally isolated from Microsphaeropsis. It inhibits adhesion of HL-60 human leukemia cells to human umbilical vein endothelial cells (HUVECs) in a concentration-dependent manner. It also inhibits the growth of SKOV3 ovarian cancer cells in a concentration-dependent manner. (+)-Macrosphelide A inhibits the growth of Gram-positive bacteria, including B. subtilis, M. luteus, B. thuringiensis, and S. aureus (MICs = 143, 143, 57, and 57 μg/ml, respectively), but not Gram-negative bacteria or fungi.

(-)-Mycousnine (Legacy Tebubio ref. 282T37553). (-)-Mycousnine is a microbial metabolite and derivative of usnic acid originally isolated fromM. nawaethat has antibacterial and antifungal activities.1,2It is active against the Gram-positive bacteriaB. subtilis,K. rhizophila, andS. aureus(MICs = 4, 8, and 4 g/ml, respectively) but not the Gram-negative bacteriaE. coli,S. typhimurium, andK. pneumoniae(MICs = >128 g/ml for all).2(-)-Mycousnine is also active against the fungiT. mentagrophytes,T. rubrum, andC. albicans(MICs = 25, 25, and 100 μg/ml, respectively).1
