Part of speech: noun

Definitions

1. A sulfonamide antibacterial compound used to treat bacterial infections by inhibiting folic acid synthesis in microorganisms ; a synthetic drug acting as an antibiotic to combat various infections ; a medicine categorized among sulfa drugs that prevents bacterial growth by targeting essential metabolic pathways
2. A chemical agent in the sulfonamide class designed to halt bacterial proliferation by interrupting folic acid production ; a pharmaceutical used in infection control owing to its antibacterial properties ; a therapeutic compound employed in the treatment of bacterial illnesses through metabolic inhibition
3. An antimicrobial substance that belongs to sulfonamide antibiotics, functioning to impede the growth of bacteria via folate synthesis disruption ; an infection-fighting medication within sulfa drugs ; a synthetic antimicrobial agent used clinically to manage bacterial diseases by metabolic interference

Etymology: Sulfapyridine is a compound name built from two chemical parts, and the first of them, "sulfa," is itself a clipped piece of "sulfanilamide," the 1930s drug that opened the era of sulfonamide antibiotics. Chemists in the 1930s and 1940s named new compounds systematically, joining the core sulfonamide stem to a second fragment that identified the added ring structure. Here "pyridine" points to the six-membered nitrogen-containing ring, a name coined in the 19th century from the Greek "pyr" (fire) and the suffix "-idine," because the compound was first obtained by heating bone oil. The drug itself was developed in the late 1930s, and its value lay in treating bacterial infections, especially pneumonia and some dysentery and meningitis cases, before penicillin became widely available. The word belongs to the pharmaceutical vocabulary of the 1930s and 1940s rather than to ordinary English, and its meaning is fixed by chemical structure rather than by any shift in sense over time.

Synonyms: sulfapyridine, antibiotic
