Title: **Leon F Christensen: Innovator in Nucleoside Chemistry**
Introduction
Leon F Christensen, a noted inventor based in Costa Mesa, California, has contributed significantly to the field of nucleoside chemistry. With a total of two patented innovations, he has made strides in the development of novel compounds that display promising activities in medical applications.
Latest Patents
Christensen's recent patents include groundbreaking processes for preparing 1,2,4-triazole nucleosides and 8-substituted cyclic nucleotides. The first patent outlines a method wherein a suitably substituted formimidic acid hydrazide is condensed with a derivative of D-ribose to create a 3-substituted-1-(blocked .beta.-D-ribofuranosyl)-1,2,4-triazole. Treatment of the intermediate with ammonia and/or the removal of its blocking group yields the desired product.
The second patent presents a novel method for synthesizing compounds with a structure that exhibits activity comparable to or surpassing that of their natural analogues while resisting degradation by phosphodiesterase. These compounds, described by a general formula, utilize a free radical alkylation and acylation process to achieve their unique properties, with some even demonstrating the ability to inhibit enzymatic degradation.
