Straightforward Synthesis of Sphinganines via a Serine-derived Weinreb Amide
摘要:
Sphinganines can be synthesized in just three steps from easily prepared serine-derived Weinreb amide 4. Pre-deprotonation of the acidic (N-H and O-H) protons of 4 allows for its efficient conversion to amino ketones 5. Such ketones can be selectively reduced to either erythro- or threo-sphinganines. Partially protected sphinganines 11 are also readily accessible in five steps from 4. Thus, Weinreb amide 4 represents one of the most versatile templates described to date for sphinganine synthesis.

The invention concerns a method and assay for qualifying equine laminitis disease status in a subject by measuring specific biomarkers, comparing the level of said biomarker to a control level; and correlating the measurement with laminitis disease status, wherein a statistically relevant elevated level of said biomarker is present in said sample relative to said control level.The invention further relates to immuno-based methods and assays for detecting toxins relevant to laminitis and to the use of antibodies for assay and diagnostic purposes.
