Plant growth retardants as inhibitors of sterol biosynthesis in tobacco seedlings.
Three plant-growth retardants 2'-isopropy1-4'-(trimethylammonium chloride)-5-methylphenylpiperidine carboxylate (Amo 1618), beta-chloroethyltrimethylammonium chloride, and tributyl-2, 4-dichlorobenzylphosphonium chloride were tested for their effects on sterol production in, and growth of tobacco (Nicotiana tabacum) seedlings. As the concentration of each retardant increased, there was an incre...
متن کاملInhibition of Abscisic Acid Biosynthesis in Cercospora rosicola by Inhibitors of Gibberellin Biosynthesis and Plant Growth Retardants.
The fungus Cercospora rosicola produces abscisic acid (ABA) as a secondary metabolite. We developed a convenient system using this fungus to determine the effects of compounds on the biosynthesis of ABA. Inasmuch as ABA and the gibberellins (GAs) both arise via the isoprenoid pathway, it was of interest to determine if inhibitors of GA biosynthesis affect ABA biosynthesis. All five putative inh...
متن کاملInhibitors of sterol biosynthesis as Staphylococcus aureus antibiotics.
One of the truisms in the medicinal chemistry of antibiotics is that there can never be enough scaffolds and structures, whether of natural or synthetic origin. No matter how successful a new antibiotic is upon clinical introduction, the inevitable selection for resistant microbes will limit its useful lifetime. Resistance to all major classes of antibiotics has been well chronicled, and one of...
متن کاملInhibition by plant growth retardants of cholesterol biosynthesis in slices of rat liver and hepatoma.
The plant growth retardant Phosfon inhibits cholesterol formation by cell·free preparations of normal liver and the Morris hepatomas 5123C, 7794A, and 9618A. In addition, both Phosfon and Amo 1618 arc active in inhibiting cholesterol synthesis from acetate and mevalonate in slices of host liver and the hepatomas. Fatty acid synthesis from acetate was also reduced in the presence of the retardants.
متن کاملAn enzymic site of inhibition of gibberellin biosynthesis by Amo 1618 and other plant growth retardants.
\Wirwille and M1itchell reported that apl)lications of 2'-isoprol)vl-4'(trimethv lammllonium chloride) -5'methylphenvl piperidine-1-carboxvlate (Amo 1618) (fig 1, I) to several types of flowNering plants led to ani abnormial growth habit characterized by shorter stemiis and initernodes (17).
