Synthesis and Characterization of Fatty Acid Conjugates of Niacin and Salicylic Acid
Abstract
This report describes the synthesis and preliminary biological characterization of novel fatty acid niacin conjugates and fatty acid salicylate conjugates. These molecular entities were created by covalently linking two bioactive molecules, either niacin or salicylic acid, to an omega-3 fatty acid. This methodology allows the simultaneous intracellular delivery of two bioactives in order to elicit a pharmacological response that could not be replicated by administering the bioactives individually or in combination. The fatty acid niacin conjugate 5 has been shown to be an inhibitor of the sterol regulatory element binding protein (SREBP), a key regulator of cholesterol metabolism proteins such as PCSK9, HMG-CoA reductase, ATP citrate lyase, and NPC1L1. On the other hand, the fatty acid salicylate conjugate 11 has been shown to have a unique anti-inflammatory profile based on its ability to modulate the NF-κB pathway through the intracellular release of the two bioactives.

The polypharmacological effect produced by simultaneous delivery of the starting chemical entities in a codrug is unique and cannot be replicated by administering multiple drugs in combinations.
“Thus, the polypharmacological effect that can be produced by the simultaneous delivery of the starting chemical entities is unique and cannot be replicated by administering multiple drugs in combinations.84”

Codrugs can provide a high level of selectivity because the two molecules are rendered essentially inactive by covalent linking.

In codrugs, the two starting chemical entities are combined via a cleavable linker that, after enzymatic biotransformation, allows their release and individual biological effects against multiple pathways in the same target cells and at the same time.
“In fact, in codrugs the two starting chemical entities are combined via a cleavable linker, which, only after enzymatic biotransformation, allows their release and their individual biological effects against multiple pathways, in the same target cells and at the same time.84”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
