Gibberellins A4/A7 (Gibberellin A4 and A7) is the Gibberellin A4 Mixture With Gibberellin A7. Gibberellins A4/A7 promotes internode elongation & breaks certain dormancies in seeds. Gibberellins A4/A7 is an endogenous plant growth regulator, promotes the growth and elongation of cells.
Pestalotin is a fungal metabolite originally isolated from P. cryptomeriaecola with diverse biological activities. It induces reducing sugar release in embryoless rice endosperms when used at concentrations ranging from 3 to 100 mg/L and enhances growth of rice seedlings (O. sativa) when used in combination with gibberellin A3 at concentrations ranging from 30 to 500 mg/L. Pestalotin has antifungal activity, reducing the growth of C. albicans, C. neoformans, T. rubrum, and A. fumigatus (MICs = 12.5, 50, 50, and 50 μg/ml, respectively). It is cytotoxic to HL-60, MKN45, LoVo, and A549 cells (IC50s = 64.87-182.92 μM). Pestalotin has been used as a standard for dereplication of natural products.
Prohexadione is a plant growth regulator. It inhibits the gibberellin plant hormone biosynthesis enzyme 3β-hydroxylase when used at concentrations of 0.1, 1, and 10 mM. It reduces the shoot length of peanut plants when applied at 0.5, 1.5, and 4.5 kg/hectare. Prohexadione also inhibits jumonji domain-containing 2A (JMJD2A) demethylase when used at a concentration of 1 mM and induces the differentiation of mouse neurospheres into neurons at 1, 1.5, and 2 mM. Formulations containing prohexadione have been used as plant growth regulators in agriculture.
