A monocationic surfactant with diverse biological activities; an inhibitor of F. tularensis AcpB (Ki = 0.59 µM) and C. albicans V-ATPase (EC50 = 69 µM); inhibits osteoclastogenesis RANKL-induced osteoclastogenesis in BMDMs; inhibits bone resorption by mature osteoclasts at 100 and 200 nM; prevents LPS-induced bone loss in a calvarial osteolytic mouse model at 5 mg/kg per day; induces mortality in C. oncophora

Thonzonium is a monocationic surfactant with diverse biological activities.{53955,53956,53957,53958} It is an inhibitor of F. tularensis acid phosphatase B (AcpB; Ki = 0.59 µM) and the vacuolar ATPase (V-ATPase) proton pump in C. albicans (EC50 = 69 µM in purified vacuolar membrane vesicles).{53955,53956} Thonzonium (25-400 nM) inhibits osteoclastogenesis induced by RANKL in bone marrow-derived macrophages (BMDMs) and inhibits bone resorption by mature osteoclasts in a V-ATPase-independent manner when used at concentrations of 100 and 200 nM.{53957} It prevents bone loss induced by LPS in a calvarial osteolytic mouse model when administered at a dose of 5 mg/kg per day. Thonzonium induces mortality in the helminths C. oncophora, O. ostertagi, H. contortus, and T. circumcincta with EC50 values of 4.5, 10.8, 5.1, and 6.7 µM, respectively, but is cytotoxic to HEK293 and RAW 264.7 cells with CC50 values of 9.2 and 5.7 µM, respectively.{53958} Formulations containing thonzonium as a surfactant have been used in the treatment of external auditory canal infections, as well as mastoidectomy and fenestration cavity infections.

  • PtdIns-(3

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 25 µg

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 50 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
