Stereochemically defined dipeptide esters of nucleoside-analogous antiviral agents including acyclovir and ganciclovir are provided. Certain of these stereochemically defined dipeptide esters are found to have unexpectedly enhanced delivery to and uptake by ocular tissues, crossing the blood-ocular barrier more effectively than other stereochemically defined dipeptide esters. For example, (L-Val)-(D-Val)-acyclovir was found to be taken up more effectively into corneal tissue than were underivatized acyclovir, monoesters (L-Val)-acyclovir or (D-Val)-acyclovir, or diester (L-Val)-(L-Val)-acyclovir.

The invention relates to hydrophilized curable silicone compositions which contain organopolysiloxanes, hydrophilizers and at least one stabilizing phosphorous compound.

An electrode substrate in which a lower electrode and an upper electrode are well positioned by way of an insulating film could not be formed by a printing method since positional displacement is caused. The cost was increased outstandingly when using photomasks for positioning. In the present invention, positional displacement does not occur even when using the printing method since the upper electrode and the lower electrode are positioned in self-alignment. Accordingly, a semiconductor device such as a flexible substrate using an organic semiconductor can be formed with low cost by using the printing method.
