Boscalid
T36141188425-85-6
Boscalid is a broad-spectrum carboxamide fungicide that inhibits fungal respiration by binding to the ubiquinone site of mitochondrial complex II/succinate dehydrogenase.1It suppresses mycelial growth ofS. minorby 87 to 100% and ofS. sclerotiorumby 77 to 100% when used at a concentration of 1 μg/ml.2In field studies, boscalid applied at 5.6 μg/cm2provides 55.5 and 30.4% disease control for lettuce drop caused byS. minorandS. sclerotiorum, respectively. It decreases cell viability of mouse primary cortical neurons following long-term exposure but is not cytotoxic (LC50= >100 μM for acute and continuous exposure). Formulations containing boscalid have been used in agriculture to prevent fungal growth on crops.

Chemical Properties
| Description | Speract, a peptide from sea urchin eggs, regulates sperm motility and stimulates sperm mitochondrial metabolism. |
| In vitro | The stimulation of sperm with speract depolarizes the mitochondrion and increases the levels of NADH.?Surprisingly, these responses are independent of external Ca(2+) and are due to the increase in intracellular pH (pHi) induced by speract.?Speract, by regulating pHi, in addition to [Ca(2+)]i, may finely modulate mitochondrial metabolism to control motility and ensure that sperm reach the egg and fertilize it[1]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
