Fluorine-containing inhibitors of matrixmetalloproteinases (MMPs) can serve as lead structures for the development of 18F-labeled radioligands. These compounds might be useful as non-invasive imaging probes to characterize pathologies associated with increased MMP activity. Results with a series of fluorinated analogs of a known biphenyl sulfonamide inhibitor have shown that fluorine can be incorporated

A series of new amino phosphonicacid derivatives of vinblastine (1, VLB) has been synthesized and tested in vitro and in vivo for antitumor activity. The compounds were obtained from O4-deacetyl-VLB azide. All of the new products studied were capable of inhibiting tubulin polymerization in vitro. The most potent antitumor compounds bore an alkyl substituent on the phosphonate. In these compounds,
Strecker-type reaction of an aldehyde, ammonium acetate and diethyl phosphite in ethanol afforded the corresponding diethyl α-aminophosphonate, a key building block of the biologically interesting phosphonopeptides, in moderate to good yield.

A new and convenient procedure has been developed for the one-pot synthesis of different types of primary 1-aminophosphonates from aldehydes/ketones, HMDS and diethyl phosphite using I-2 as an inexpensive, non-toxic, non-metallic and readily available catalyst. These reactions proceeded under solvent-free conditions and produced the desired products in high yields.
