We describe a method of growing an animal cell in a culture medium, in which the culture medium comprises an elevated concentration of a thymidine family member, in which the growth or viability of the animal cell is increased as a result of the elevated concentration of the thymidine family member in the cell culture medium. Preferably, the cell culture medium comprises a semi-solid medium, which is a serum free or chemically defined medium.

allyl (5) derivatives exerted hypnotic activity, although the derivatives tested (2-10) significantly prolonged the pentobarbital-induced sleeping time. Compound 1 and its xylyl derivatives tested (0.25 mumol/mouse, i.c.v.) decreased locomotor activity. These results indicate that thymidine derivatives have central depressant activity, and the benzyl derivatives but not alkyl derivatives possess a
