An opportunity of designing nontypical double-stranded DNA structures containing nonnatural inserts in a regular nucleotide DNA sequence has been investigated. The looped nucleotide inserts on the basis of adenylates and thymidilates, and nonnucleotide inserts on the basis of phosphodiesters of
Poly(ortho esters) with a low glass transition temperature are semi-solid materials so that therapeutic agents can be incorporated at room temperature, without the use of solvents, by a simple mixing procedure. When molecular weights are limited to < 5 kDa

The synthesis of poly(ortho-esters) (POEs) containing lactic acid dimers in the polymer backbone for possible use in controlled drug release applications is described. These autocatalyzed POEs are prepared by the acid catalyzed condensation of 3,9-diethylidene-2,4,8,10-tetraoxaspiro(5,5)undecane with diols to produce linear
