(1) Cultured confluent human umbilical vein endothelial cells were incubated with new-breviscapine (NB), a flavonoid consisting of 4-OH-scutellarin-7-O-glucuronide (C33H30O18) and FeCl3, MgCl2, and CaCl2, which is first extracted from Erigeron breviscapus (Vant) Hand-Mazz in China, 0, 6.25, 12.5, 25, 50, 100, and 1,000 micrograms.ml-1.
(2) Boyle-vant Hoff plots of cell volume as a function of inverse osmotic pressure showed that the cells behaved as osmometers.
(3) Enthalpies of solution in water, delta H0sol, and vant'Hoff enthalpies of sublimation, delta H0subl, were determined experimentally for a number of crystalline 2-alkyl derivatives of 9-methyladenine: m2(2,9)Ade, e2m9Ade, pr2m9Ade and but2m9Ade.
