General Description
Pisatin is a phytoalexin, a class of natural product synthesized by plants in response to microbial infection. It is a biphenyl compound containing a hydroxyl group and is found in high levels in the roots of the garden pea (Pisum sativum), from which it takes its name. Pisatin exhibits antifungal properties and is considered a key component of the plant's defense mechanism against pathogen attack. Research has shown that pisatin can inhibit the growth of a wide range of fungi, making it a potentially valuable substance for agricultural and pharmaceutical applications. Additionally, pisatin has been found to induce defense-related genes in plants, further enhancing their ability to resist disease. Overall, pisatin plays a crucial role in the plant's immune response and has the potential to be harnessed for various beneficial purposes.
Check Digit Verification of cas no
The CAS Registry Mumber 20186-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,8 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20186-22:
(7*2)+(6*0)+(5*1)+(4*8)+(3*6)+(2*2)+(1*2)=75
75 % 10 = 5
So 20186-22-5 is a valid CAS Registry Number.

Syntheses of Pterocarpans, II. - Synthesis of Both the Enantiomers of Pisatin
Mori, Kenji,Kisida, Hirosi
, p. 35 - 40 (2007/10/02)
The first synthesis of (+)-pisatin was achieved by resolving (+/-)-6, which in turn was prepared from the isoflavone derivative 1.The unnatural (-)-pisatin was also synthesized.
