Anticoccidial riboflavine antagonists
Experientia, 19774 types of riboflavine antagonists have broad-spectrum activity in poultry coccidiosis. 5-Deazariboflavine is most effective. 10-Benzyl analogs of riboflavine control intestinal species of coccidia.

Journal of Medicinal Chemistry, 1977
Of the nine nitropyridinecarboxamides, which are isomers of 5-nitronicotinamide, a potent anticoccidial agent, 2-nitropyridine-3, -4, -5-, or 6-carboxamides and 3-nitropyridine-4- or 6-carboxamides were prepared from the corresponding acids via the esters of the acid chlorides. 3-Nitropyridine-2-carboxamide was obtained from 2-methyl-3-nitropyridine by

Anticoccidial Effects of Xanthohumol
Avian Diseases Digest, 2007Xanthohumol (XN), a prenylated chalcone from the hops flower, was examined for its ability to reduce invasion of Madin-Darby bovine kidney (MDBK) cells by Eimeria tenella sporozoites (SZ), as well as to reduce invasion by E. tenella and E. acervulina SZ in the chick host.

Anticoccidial Activity of Nicotinamide Antagonists
Nature, 1965THE life-cycle of poultry coccidia can be inhibited by certain p-aminobenzoic acid1–3, folic acid3–6 and thiamine7 antagonists. This knowledge led to our testing three known antagonists of another vitamin, nicotinamide, for anticoccidial activity. These substances were 3-acetylpyridine8, pyridine-3-sulphonamide9 and 6-aminonicotinamide10.

Anticoccidial activity of 1-phenyluracils
Journal of Medicinal Chemistry, 1983The minimum effective concentration (MEC) of 6-azauracil against Eimeria tenella when incorporated in feed is about 1000 ppm. Attachment of suitably substituted phenyl side chains at the 1-position reduces the MEC to less than 1 ppm. Uracil itself is devoid of anticoccidial activity, but side chains attached at the 1-position potentiate uracil and ...

Anticoccidial Effects of Ageratum conyzoides
Journal of Ethnopharmacology, 2009Ageratum conyzoides (Asteraceae) is folklorically used to treat diseases associated with bleeding. A study was conducted to determine the efficacy of Ageratum conyzoides in treating caecal coccidiosis of broilers. Acute toxicity test was done using thirty 28 days old broiler chicks which were divided into six groups of five birds each.

Anticoccidial activity of crown polyethers
Journal of Medicinal Chemistry, 1983Anticoccidial activity in vitro against Eimeria tenella is reported for crown polyethers with ring sizes from 14 to 30 atoms. The most potent compounds, 4 and 9, were found active at 0.33 ppm, but none were active in vivo. Test results are discussed in terms of lipophilic shielding of complexed cations.

Anticoccidial activity of arprinocid and halofuginone
Veterinary Parasitology, 1981Halofuginone and arprinocid, new anticoccidial drugs, were tested to determine the time of peak activity in the life cycle of Eimeria and whether they were coccidiocidal or coccidiostatic. Halofuginone was completely effective if medication was initiated by Day 3 postinoculation, but only partly effective if given on Days 4-7.

8-Aminoquinolines as anticoccidials — II
Bioorganic & Medicinal Chemistry Letters, 1998During a chemistry program aimed at finding a novel analogue of pentaquine with improved in vivo activity, a number of hypotheses concerning the way this drug acts in the chicken were investigated. Consideration of the products of monoamine oxidase metabolism of pentaquine suggested that pentaquine aldehyde is the likely active metabolite.
