- Tubulin assembly into microtubules results in an increase in turbidity observed at 350 nm using a spectrophotometer.
- 3- (3-hyd-Oxy-4-methoxy-benzyl) -7-methylene-1-vinyl-2,3,3a, 4,7,7a- hexahydro-indene-4-one and 3- (3 -hydroxy-4-methoxy-benzyl) -4-hydroxy-7-methyl-1-vinyl-indane cause an inhibition of tubulin polymerization which results in an increase in latency, a decrease in the rate of polymerization as well as a lower turbidity in the stationary state.
- the product thus obtained is taken up in 5 cm3 of a dichloromethane-methanol mixture (99-1 by volume) and chromatography on a column of 50 g Merck 60H silica, for which the diameter / height ratio is equal to 15, prepared with the same solvent. Eluted with a dichloromethane-methanol mixture (99-1 by volume), collecting fractions of 2 cm3. Fractions 41 to 68 are combined and concentrated to dryness under reduced pressure.
- the ethereal solution thus obtained is concentrated to a volume of 15 liters in a thermosiphon evaporator, then concentrated to dryness under reduced pressure at 40 ° C.
- the product obtained can be viewed by chromatography on a thin layer of Merck F254 silica, eluting with a dichloromethane-methanol mixture (99-1 by volume) and development by the GIBBS reagent specific for phenols.
- 3- (3-hydroxy-4-me oxy-ber-2yl) -7-methylene-1-vinyl-2,3,3a, 4,7,7a-hexa- hydro-indene-4-one and 3 - (3-hydroxy-4-methoxy-benzyl) -4-hydroxy-7-methyl-1-vinyl-indane exhibit significant inhibitory activity on abnormal cell proliferation and has therapeutic properties allowing the treatment of patients with conditions pathologies associated with abnormal cell proliferation.
