ascr#1
An (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (6R)-6-hydroxyheptanoic acid with ascarylopyranose (the alpha anomer). It is a major component of the dauer pheromone, used by the nematode Caenorhabditis elegans as a population-density signal to promote entry into an alternate larval stage, the nonfeeding and highly persistent dauer diapause. It has also been found in Pristionchus pacificus and the sour paste nematode Panagrellus redivivus. CONFIDENCE standard compound; INTERNAL_ID 97
ascr#2
A hydroxy ketone ascaroside obtained by formal condensation of the hydroxy group of (5R)-5-hydroxyhexan-2-one with ascarylopyranose (the alpha anomer). It is a major component of the dauer pheromone, used by the nematode Caenorhabditis elegans as a population-density signal to promote entry into an alternate larval stage, the nonfeeding and highly persistent dauer diapause, and also synergises with ascr#3, ascr#4, and ascr#8 in male attraction. Ascr#2 is an ascaroside isolated from Caenorhabditis elegans, potently promotes dauer formation, and also acts as a potent male attractant combined with ascr#3 at low concentration[1].
ascr#3
An (omega-1)-hydroxy fatty acid ascaroside obtained by formal condensation of the alcoholic hydroxy group of (2E,8R)-8-hydroxynon-2-enoic acid with ascarylopyranose (the alpha anomer). It is a major component of the dauer pheromone, used by the nematode Caenorhabditis elegans as a population-density signal to promote entry into an alternate larval stage, the nonfeeding and highly persistent dauer diapause, and also synergises with ascr#2, ascr#4, and ascr#8 in male attraction.
icas#9
A 4-O-(1H-indol-3-ylcarbonyl)ascaroside derived from (4R)-4-hydroxypentanoic acid. It is a metabolite of the nematode Caenorhabditis elegans.
