Cis-4-Hydroxy-D-proline may be used as a starting material for the 13-step synthesis of new conformationally restricted PNA adenine monomer and the synthesis of N-Benzyl pyrrolidinyl sordaricin derivatives. Cis-4-Hydroxy-D-proline is a substrate that may be used to study the specificity and kinetics of D-alanine dehydrogenase. Cis-4-Hydroxy-D-proline may be used to analyze the substrate specificity of amino acid transporter PAT1.
[reaction:see text] A new conformationally restricted PNA adenine monomer has been synthesized in 13 steps from cis-4-hydroxy-D-proline. A fully modified adenine decamer displayed improved binding affinity toward complementary DNA and RNA oligonucleotides as compared to that of the parent PNA
N-Benzyl pyrrolidinyl sordaricin derivatives have been synthesized from cis-4-hydroxy-D-proline in a stereocontrolled manner. These compounds maintained moderate antifungal activity against several pathogenic fungal strains. Their MIC values against Candida albicans were in the range of 0.25-2 microg/mL.
The proton coupled amino acid transporter PAT1 expressed in intestine, brain, and other organs accepts L- and D-proline, glycine, and L-alanine but also pharmaceutically active amino acid derivatives such as 3-amino-1-propanesulfonic acid, L-azetidine-2-carboxylic acid, and cis-4-hydroxy-D-proline as substrates. We systematically
3,4-Dehydro-DL-proline is a toxic analogue of L-proline which has been useful in studying the uptake and metabolism of this key amino acid. When membrane fractions from Escherichia coli strain UMM5 (putA1::Tn5 proC24) lacking both L-proline dehydrogenase and L-Delta(1)-pyrroline-5-carboxylate reductase were

Proline utilization A (PutA) proteins are bifunctional proline catabolic enzymes that catalyze the 4-electron oxidation of l-proline to l-glutamate using spatially-separated proline dehydrogenase and l-glutamate-γ-semialdehyde dehydrogenase (GSALDH, a.k.a. ALDH4A1) active sites. The observation that l-proline inhibits both the GSALDH activity
