Succinylsulfathiazole (Succinylsulphathiazole) is a long-acting sulfonamide antibiotic with localized gut-specific antibacterial activity and is orally active. Succinylsulfathiazole inhibits bacterial folate synthesis, reduces coliform counts, suppresses intestinal bacterial growth and vitamin biosynthesis, and depletes gut folate-producing bacteria. Succinylsulfathiazole modulates hepatic mTOR signaling, diminishes cecal fermentation, decreases hepatic folate levels and total folate excretion, elevates nitrogen excretion and reduces the fermentability of certain dietary fibers. Succinylsulfathiazole induces folate deficiency and triggers biotin- and folate-related nutritional deficiency symptoms in rats and C57BL/6 mice.

Succinylsulfathiazole (2%; 119 days) causes a significant, variable reduction in fecal coliform counts but no significant changes in total aerobic organisms, total anaerobic organisms, or anaerobic spore counts in Sunny Hill strain piebald rats^[3].
Succinylsulfathiazole (2%) reduces fecal excretion of biotin, folic acid, and pantothenic acid compared to unsupplemented stock or purified diets in Sunny Hill strain piebald rats^[3].
Succinylsulfathiazole (2%; 3 days) reduces fecal coliform counts, with no significant changes in total aerobic organisms, total anaerobic organisms, or anaerobic spore counts in Albino Farms strain rats^[3].
Succinylsulfathiazole (1%; oral consumption; daily; 21 weeks) modulates key components of the PI3K/AKT/mTOR signaling pathway and energy metabolism regulators in C57BL/6 mouse liver (with differential effects on REDD1 expression in folate adequate vs. depleted mice)^[1].
Succinylsulfathiazole (5 g/kg; oral; ad libitum; 27-29 days) reduces fecal folate excretion, lowers liver folate stores, decreases markers of bacterial growth, and alters cecal short-chain fatty acid production in folate-depleted Sprague-Dawley rats during folate repletion^[2].
Succinylsulfathiazole (2% w/w; oral; continuous feeding; 119 days) reduces fecal coliform counts, lowers fecal biotin and folic acid excretion, and induces leukopenia^[3].
Succinylsulfathiazole (0.5-2% w/w; oral; continuous feeding) reduces fecal coliform counts^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

C57BL/6 (male, specific pathogen-free, 6 weeks at purchase, studied at 4 months)^[1]
Dosage:

1% (incorporated into purified isoenergetic diets, folate adequate: 2 mg folate/kg diet; folate depleted: 0 mg folate/kg diet)
Administration:

oral consumption; daily; 21 weeks
Result:

Showed no significant difference in body weight gain or food consumption over 21 weeks.
Exhibited no significant differences in folate levels across serum, liver and colon tissues versus untreated controls.
In folate-adequate mice: significantly reduced PDK1 expression and mTORc1 phosphorylation at Ser2448, elevated REDD1 expression, and lowered the ADP/ATP ratio and AMPK phosphorylation.
In folate-depleted mice: significantly decreased REDD1 expression, the ADP/ATP ratio and AMPK phosphorylation.
Reduced 4E-BP1 phosphorylation in both dietary groups.Showed no significant effects on AKT expression, mTORc1 autophosphorylation at Ser2481, S6K1 phosphorylation, autophagy-related proteins (Beclin, ATG5, LC3 cleavage), the NAD+/NADH ratio or SIRT1 expression in either group.

Animal Model:

Sprague-Dawley (male weanling, initial weight 45.3 g, folate-depleted by low-folacin AIN93G basal diet for 28 days)^[2]
Dosage:

5 g/kg diet
Administration:

oral; ad libitum; 27-29 days
Result:

Reduced total folate excretion from 13.8 to 4.8 nmol/d (pooled diets).
Lowered mean liver folate concentration from 11.6 to 7.5 nmol/g (pooled diets); this reduction was significant in rats fed standard, ground corn, wheat germ, inulin and polydextrose diets, but not in those fed wheat bran or oat bran diets.
Decreased diaminopimelic acid and muramic acid excretion, and increased nitrogen excretion (pooled diets).
Reduced fermentability of oat bran, ground corn, and wheat germ fibers; had no effect on wheat bran fiber, inulin, or polydextrose fermentability.
Lowered cecal acetic acid and propionic acid contents overall, with a diet×antibiotic interaction for propionic acid.

Animal Model:

Sunny Hill strain piebald rats (~75 days old when placed on succinylsulfathiazole diet)^[3]
Dosage:

2% w/w
Administration:

oral; continuous feeding; 119 days
Result:

Dropped fecal coliform counts immediately, with one rat averaging 10⁵ per gram feces, another averaging 10³ per gram feces with wide fluctuation (0-10⁸), and the third having feces almost entirely devoid of coliforms until near the end of the experiment when counts rose to 10⁴ per gram.
Showed no significant change in total aerobic and anaerobic organism counts, and anaerobic spore counts compared to pre-drug diet levels.
Reduced fecal excretion of biotin to 0.28 μg/gm feces and 0.39 μg/day, and folic acid to 2.5 μg/gm feces and 4.2 μg/day, significantly lower than in rats fed stock or purified diets without succinylsulfathiazole.
Induced low total leucocyte counts prior to vitamin supplementation.

Animal Model:

Albino Farms strain rats (~60 days old when placed on succinylsulfathiazole diet)^[3]
Dosage:

0.5% w/w; 2% w/w
Administration:

oral; continuous feeding
Result:

Reduced fecal coliform counts to a low level with 2% w/w diet, though this reduction occurred more slowly than with an equivalent level of phthalylsulfathiazole.
Resulted in fecal coliform counts < 10⁴ per gram feces after 3 days of feeding with 0.5% w/w diet.
Showed no significant change in total aerobic and anaerobic organism counts, and anaerobic spore counts compared to pre-drug diet levels.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
