Sulfamethoxazole is a sulfonamide antibiotic.{38582} It inhibits growth of E. coli (MIC = 10 μg/ml) and clinical isolates of methicillin-resistant S. aureus (MRSA; MICs = 25-50 μg/ml).{38583,38584} Sulfamethoxazole, in combination with trimethoprim (Item No. 16473) at a ratio of 20:1, inhibits growth of MRSA in vivo in mice (MIC = 0.8 μg/ml; ED50s = 6.4 and 9.6 mg/kg for two MRSA strains).{38584} In a mouse model of urinary tract infection with E. coli, a combination of sulfamethoxazole and trimethoprim decreases recurrent infection when administered for 10 days.{38585} Sulfamethoxazole acts by inhibiting dihydropteroate synthase (DHPS), which converts a pteridine and 4-aminobenzoic acid (PABA; Item No. 18659) to dihydropteroate, an intermediate in folate biosynthesis. It inhibits recombinant P. carinii DHPS (IC50 = 23 nM; Ki = 7.5 nM) and folate biosynthesis in situ by 48.6%. Formulations containing sulfamethoxazole and trimethoprim have been used to treat bronchitis, prostatitis, and urinary tract infections among other infectious conditions.

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

    Anhydrotetracycline (hydrochloride) – 500 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}
