Disclosed herein, inter alia, are prodrug compositions and methods of using the same for treatment and detection of disease. Specifically, disclosed herein is a compound of formula (I) having spiro-fused 1,2,4-trioxolane and piperidine rings, namely, 1,2,4-trioxa- 8-azaspiro[4.5] decane. Also disclosed is a pharmaceutical composition containing the compound and a phannaceutically acceptable carrier.
A gramineous plant having tolerance to iron deficiency which can grow even in an area with ion deficiency. More particularly, a gramineous plant having tolerance to iron deficiency and capable of vigorously growing even in calcareous alkaline soil which is constructed by transferring a gene of an enzyme in the pathway of the biosynthesis of mugineic acids in gramineous plants into a gramineous plant. A method of constructing a gramineous plant having improved iron absorbability which comprises transferring a gene encoding an enzyme (preferably nicotianamine aminotransferase; NAAT) in the pathway of the biosynthesis of mugineic acids into a gramineous plant; a gramineous plant constructed by the above method; a method of cultivating the above gramineous plant having improved iron absorbability; and a crop obtained by the cultivation. Namely, the constructing of a novel gramineous plant having tolerance to iron deficiency.
A reductase reducing keto-nicotianamine into 2'-deoxymugineic acid in the course of the biosynthesis of mugineic. acids participating in the iron-acquisition mechanism in plants; a gene encoding this enzyme; a plant having a enhanced tolerance to iron-deficiency owing to the above gene transferred thereinto; and enzyme kits and gene kits for constructing a plant having a enhanced tolerance to iron-deficiency which comprise enzymes for biosynthesizing mugineic acids participating in the iron-acquisition mechanism in plants or genes encoding these enzymes.
