摘要： Specific PEHAM dendrimers are used in a formulation with an active agent for agricultural purposes, particularly for increasing the efficacy of the active agent in various ways, such as by improving solubility of the active agent in the formulation, by improving adhesion and penetration of the active agent to plant surfaces, by improving the water-fastness of the active agent to the plant or seed, by increasing soil penetration of the active agent to reach the plant roots or under soil parts, or by reducing soil adhesion of the active agent to reach the plant roots or under soil parts, or reducing enzymatic degradation of the active agent by the plant or seed or microorganisms in the soil.

摘要： This invention provides a cost effective process and new Janus dendrimers where at least two dendrons are attached at the core (with or without a connector group) and where at least two of the dendrons have different functionality. Preferred are those Janus dendrimers where at least one dendron is a PEHAM dendron. Thus these Janus dendrimers are heterobifunctional in character and use unique ligation chemistry with single site functional dendrons, di-dendrons and multi-dendrons. Also included are Janus dendrons which may be used as intermediates to make the Janus dendrimers or to further react with another reactive moiety. These Janus dendrimers can provide several new dendrimer moieties, namely: combinatorial libraries of bifunctional structures; combined target director and signaling dendrimers; specific targeting entities for diagnostic and therapeutic applications, such as for example targeted MRI agents, targeted radionuclide delivery for diseases such as cancer, and targeted photosensitive or radiowave sensitive agents.
