The present invention relates to using a versatile synthetic approach to generate a new class of ester, amido, or carbamate prodrugs of highly potent, but systemically too toxic, platinum-acridine anticancer agents. The new hybrids contain a hydroxyl group, which has been masked with a cleavable lipophilic acyl moiety. Both butanoic (butyric) and bulkier 2-propanepentanoic (valproic) esters were introduced to these compounds. The goal of this design was to improve the drug-like properties of the pharmacophore (e. g., log D) without compromising its DNA-mediated cell kill potential. Two distinct pathways by which the target compounds undergo effective ester hydrolysis, the proposed activating step, have been confirmed: platinum-mediated, self-immolative ester cleavage in a low-chloride environment (LC-ESMS, NMR spectroscopy) and enzymatic cleavage by human carboxylesterase-2 (hCES-2) (LC-ESMS). Several of the new compounds show excellent stability, reduced systemic toxicity, and favorable activation profiles while maintaining submicromolar cytotoxicity in various cancers, such as lung adenocarcinoma cell lines (A549, NCI-H1435). The results suggest that the novel dual-mode prodrug concept may have the potential to hasten the preclinical development of platinum-acridines.

The invention discloses a freeze-dried preparation and a preparation method and applications thereof. The mass percentage of triterpenoid saponin in the freeze-dried preparation is 0.004-95%, and themass percentage of a binder in the freeze-dried preparation is 0.01-99%. The freeze-dried preparation is prepared by freeze-drying a pre-blended solution containing the triterpenoid saponin and the binder. When the mass percentage of the triterpenoid saponin in the pre-blended solution is 0.001-50% and the mass percentage of the binder in the pre-blended solution is 0.01-50%, and the mass of the triterpenoid saponin increases along with the increase of the mass of the binder; and when the mass percentage of the triterpenoid saponin in the pre-blended solution is 50-95% and the mass percentageof the binder in the pre-blended solution is 0.01-20%, the mass of the triterpenoid saponin decreases with the increase of the mass of the binder. When used as an oral preparation, a solid beverage ora non-washing skin care product, the freeze-dried preparation has the advantage of quick disintegration.

It is an object of the present invention to provide improved pharmacological properties to molecules which bind to a target with low affinity (hereinafter referred to as a “ligand moiety”) through linkage of such molecules to a metal binding moiety, thereby generating a combination molecule commonly referred to as a “metallodrug” or “metallotherapeutic.” The metal binding domain of metallodrugs typically catalyzes oxido-reductase chemistry or acts as a Lewis-Acid catalyst, resulting in modification of proteins and nucleic acids that are in close proximity due to binding of the ligand moiety to its target.
