Uses
A potent and selective platlet activating factor
Biological Activity
(±)trans-2,5-bis-(3,4,5-trimethoxyphenyl)-1,3-dioxolane, also known as trans-btp dioxolane, is a paf receptor antagonist [1].platelet activating factor (paf), a phospholipid mediator of inflammation, is secreted by several cell types including arterial endothelial cells, and can activate polymorphonuclear leucocytes and monocytes via specific cell surface receptors. paf also stimulates the production of active oxygen species by human monocyte - derived macrophages. paf play important roles in a variety of pathophysiological states including acute allergy, inflammation, asthma, gastrointestinal ulceration, and toxic shock [1].(±)trans-2,5-bis-(3,4,5-trimethoxyphenyl)-1,3-dioxolane is a paf receptor antagonist. in the rabbit washed platelet assay, (±)trans-2,5-bis-(3,4,5-trimethoxyphenyl)-1,3-dioxolane showed good competitive paf antagonism with ki value of 0.3 μm, whereas the cis-isomer was much less active.

Check Digit Verification of cas no
The CAS Registry Mumber 116673-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,6,7 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116673-45:
(8*1)+(7*1)+(6*6)+(5*6)+(4*7)+(3*3)+(2*4)+(1*5)=131
131 % 10 = 1
So 116673-45-1 is a valid CAS Registry Number.
