branched-chain amino acids. Earlier gene mutation of Candida albicans in a mouse model suggested that this enzyme is a promising target of antifungals. Recent studies have demonstrated that some commercial AHAS-inhibiting sulfonylurea herbicides exerted desirable antifungal activity. In this study, we have designed and synthesized 68 novel ethoxysulfulron (ES) derivatives and evaluated their inhibition

have designed and synthesized a series of 42 novel sulfonylurea compounds with ortho-alkoxy substitutions at the phenyl ring and evaluated their herbicidalactivities. Some target compounds showed excellent herbicidalactivity against monocotyledon weed species. When applied at 7.5 g ha–1, 6–11 exhibited more potent herbicidalactivity against barnyard grass (Echinochloa crus-galli) and crab grass (Digitaria
Specific iodopyrimidine compounds such as 2-[[(4-iodo-6-methoxypyrimidin-2-yl)aminocarbonyl]-aminosulfonyl]benzoic acid, methyl ester and N'-[(4-iodo-6-methoxypyrimidin-2-yl)aminocarbonyl]-N,N-dimethyl-1,2-benzen edisulfonamide are active preemergent and postemergent herbicides and plant growth regulants.

assay. Among the target compounds, 6e showed desirable antifungal activity against Candida albicans standard isolate sc5314 with minimum inhibition concentration (MIC) of 0.39 mg/L (0.98 μM) after 24 h, and 6a demonstrated promising pre-emergence herbicidal activity against Echinochloacrus-galli at 30 g/ha dosage. Representative compounds 6a, 6e, and 6i showed no cell cytotoxicity even at 40 mg/L concentration
