480-49-9 Usage
Description
FILIPIN III, a macrolide and the major component of the filipin complex, is a potent broad-spectrum antifungal agent derived from Streptomyces filipinensis. It exhibits antifungal, antitumor, and antiviral activities by binding to cell membrane sterols, disrupting membrane integrity. This sterol selectivity has made it a valuable diagnostic probe for quantifying cholesterol in mammalian cells.
Uses
Used in Antifungal Applications:
FILIPIN III is used as an antifungal agent for its potent broad-spectrum activity against various fungal infections.
Used in Antitumor Applications:
FILIPIN III is used as an antiviral agent for its demonstrated antitumor properties.
Used in Diagnostics:
FILIPIN III is used as a diagnostic probe for quantifying cholesterol in mammalian cells due to its sterol selectivity and ability to bind to cholesterol in membranes.
Used in Research:
FILIPIN III is used as a sterol probe in freeze-fracture cytochemistry for the localization and measurement of cholesterol in cells.
Used in Arthritis Research:
FILIPIN III is used to produce arthritis rapidly in rabbits for research purposes, as reported in Drug Trade News on July 4, 1966.
Biochem/physiol Actions
Filipin is a polyene macrolide antibiotic and antifungal. The antifungal mechanism of action may be due to altering membrane permeability and associated functions by binding to membrane sterols. Filipin inhibits prion protein (PrP) endocytosis and causes the release of PrP from the plasma membrane.

Check Digit Verification of cas no
The CAS Registry Mumber 480-49-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 480-49:
(5*4)+(4*8)+(3*0)+(2*4)+(1*9)=69
69 % 10 = 9
So 480-49-9 is a valid CAS Registry Number.

Total synthesis of Filipin III
Richardson, Timothy I.,Rychnovsky, Scott D.
, p. 8977 - 8996 (2007/10/03)
Filipin III (1), a polyene macrolide antibiotic, has been synthesized for the first time. The polyol chain was assembled using a stereoselective carbon-carbon bond forming strategy previously developed in our lab: a cyanohydrin acetonide alkylation and reductive decyanation sequence. The polyene segment was prepared from L-ascorbic acid. These two components were coupled using Yamaguchi's esterification, and cyclized with an intramolecular Horner-Emmons reaction to form a trisubstituted alkene. Stereoselective reduction followed by deprotection gave filipin III. This highly convergent approach to filipin III represents the first total synthesis of a methylpentaene macrolide antibiotic.
