Sulfamethoxazole sodium (Ro 4-2130 sodium) is a sulfonamide bacteriostatic antibiotic.

Lamivudine (BCH-189) is a reverse transcriptase inhibitor and ZALCITABINE analog in which a sulfur atom replaces the 3' carbon of the pentose ring. It is used to treat HIV disease.

Doxycycline (Doxiciclina) belongs to the tetracycline class of antibiotics and is a broad-spectrum metalloproteinase (MMP) inhibitor with oral activity. Doxycycline has antibacterial activity and antitumor activity.

Guanidine hydrochloride (Aminoformamidine Hydrochloride) is a strong organic base existing primarily as guanidium ions at physiological pH. It is found in the urine as a normal product of protein metabolism. It is also used in laboratory research as a protein denaturant.

Kanamycin sulfate (Kanamycin monosulfate) is an aminoglycoside antibiotic that interferes with protein synthesis by binding to the 70S ribosomal subunit of bacteria. Kanamycin sulfate exhibits antimicrobial activity against both Gram-positive and Gram-negative bacteria, as well as mycoplasmas.

Stavudine (BMY-27857), a nucleoside reverse transcriptase inhibitor analog of thymidine, has activity against HIV.

Ampicillin Sodium is the sodium salt form of ampicillin, a broad-spectrum semisynthetic derivative of aminopenicillin. Ampicillin sodium (Domicillin) inhibits bacterial cell wall synthesis by binding to penicillin binding proteins, thereby inhibiting peptidoglycan synthesis, a critical component of the bacterial cell wall.

Dextran sulfate sodium salt (MW 4500-5500) is an anhydrous glucose polymer with a molecular weight range of 4500-5500. It inhibits human immunodeficiency virus replication by preventing viral adsorption to host cells and is commonly used to model inflammatory bowel disease. The high negative charge from its sulfate groups damages the intestinal mucosal barrier, leading to intestinal barrier dysfunction, macrophage impairment, and bacterial flora disorder.
