Y18501

Catalog No. T79336 CAS 2410627-32-4

Y18501, an oxysterol-binding protein (OSBPI) inhibitor structurally akin to Oxathiapiprolin, demonstrates potent inhibition against Phytophthora spp. and Pseudoperonospora cubensis with EC50 values between 0.0005 and 0.0046 μg/mL. It exhibits exceptional protective and curative effects on P. cubensis. When used in tandem with Chlorothalonil, Y18501 markedly enhances the suppression of P. cubensis [1].

Description

In vitro

Y18501, at application rates of either 25 g a.i./ha or 50 g a.i./ha, demonstrated control efficacy exceeding 60% against cucumber downy mildew under greenhouse conditions [1]. In both greenhouse and field settings, Y18501 exhibited control efficacies of 72.3% and 78.9% at 25 g a.i./ha, and 80.8% and 82.2% at 50 g a.i./ha, respectively [1]. The protective activity of Y1850 (10.012-0.333 μg/mL) was greater than its curative activity; treatment with Y1850 24 hours prior to inoculation resulted in control efficacies of 70.11 and 99.43%, significantly higher than treatments administered 24 hours post-inoculation [1]. Synergistic effects against cucumber downy mildew were noted when Y18501 was combined with Chlorothalonil at ratios of 1:100, 1:70, and 1:50, with synergy ratios of 2.00, 1.83, and 2.64, respectively [1].

Molarity Calculator allows you to calculate the

Mass of a compound required to prepare a solution of known volume and concentration
Volume of solution required to dissolve a compound of known mass to a desired concentration
Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
