| abstract |
A composition for chemically treating a target condition, existing at a microenvironment localized within an environment, with an active compound, the composition comprising precursor components which can conjugate covalently to form the active compound in situ, and for which the covalent conjugation is more favourable at the microenvironment of the target condition than in the surrounding environment. Disclosed examples include biologically-active compounds which are preferentially formed in the microenvironment of tumour cells. |
