Delivery of cholesteryl-conjugated phosphorothioate oligodeoxynucleotides to Kupffer cells by lactosylated low-density lipoprotein

The efficacy of antisense oligonucleotides depends on the ability to reach in vivo their target cells. We aim to develop strategies to enhance uptake of phosphorothioate oligodeoxynucleotides by Kupffer cells. To this end, we conjugated cholesterol to ISIS-3082, a phosphorothioate oligodeoxynucleotide specific for intercellular adhesion molecule-1. The cholesterol-conjugated oligonucleotide, denoted ISIS-9388, associated readily with lactosylated low-density lipoprotein (LacLDL), a lipidic carrier that is taken up by galactose receptors on Kupffer cells. Association of up to 10 molecules of ISIS-9388 per LacLDL particle did not induce aggregation. LacLDL-associated [3H]ISIS-9388 was rapidly taken up by the liver after injection into rats (52.9 ± 1.8% of the dose within 2 min versus 18.6 ± 2.8% for ISIS-3082). N-acetylgalactosamine inhibited hepatic uptake, indicating involvement of galactose-specific receptors. Liver cells were isolated at 60 min after injection of LacLDL-associated [3H]ISIS-9388. Kupffer cells displayed the highest uptake: 88.1 ± 24.7 ng of oligonucleotide/mg of cell protein, which is 6-14 times higher than after injection of free ISIS-9388 or ISIS-3082 (15.0 ± 3.8 ng and 6.3 ± 1.4 ng, respectively). It can be calculated that Kupffer cells contribute 43.9 ± 5.4% to the liver uptake (free ISIS-9388 and ISIS-3083 14.5 ± 3.1% and 8.3 ± 3.2%, respectively). In conclusion, conjugation of a phosphorothioate oligodeoxynucleotide with cholesterol and its subsequent association with LacLDL results in a substantially increased Kupffer cell uptake of the oligonucleotide. As Kupffer cells play a key role in inflammation, our approach may be utilized to improve antisense-based therapeutic intervention during inflammation.

Low calorie sweeteners differ in their physiological effects in humans

Low calorie sweeteners (LCS) are prevalent in the food supply for their primary functional property of providing sweetness with little or no energy. Though tested for safety individually, there has been extremely limited work on the efficacy of each LCS. It is commonly assumed all LCS act similarly in their behavioral and physiological effects. However, each LCS has its own chemical structure that influences its metabolism, making each LCS unique in its potential effects on body weight, energy intake, and appetite. LCS may have different behavioral and physiological effects mediated at the sweet taste receptor, in brain activation, with gut hormones, at the microbiota and on appetitive responses. Further elucidation of the unique effects of the different commercially available LCS may hold important implications for recommendations about their use for different health outcomes.

Profiling and Application of Photoredox C(sp3)-C(sp2) Cross-Coupling in Medicinal Chemistry

Recent visible-light photoredox catalyzed C(sp3)-C(sp2) cross-coupling provides a novel transformation to potentially enable the synthesis of medicinal chemistry targets. Here, we report a profiling study of photocatalytic C(sp3)-C(sp2) cross-coupling, both decarboxylative coupling and cross-electrophile coupling, with 18 pharmaceutically relevant aryl halides by using either Kessil lamp or our newly developed integrated photoreactor. Integrated photoreactor accelerates reaction rate and improves reaction success rate. Cross-electrophile coupling gives higher success rate with broad substrate scope on alkyl halides than that of the decarboxylative coupling. In addition, a successful application example on a discovery program demonstrates the efficient synthesis of medicinal chemistry targets via photocatalytic C(sp3)-C(sp2) cross-coupling by using our integrated photoreactor.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C7H12O3, you can also check out more blogs about233276-38-5

17(R),18(S)-Epoxyeicosatetraenoic acid, a potent eicosapentaenoic acid (EPA) derived regulator of cardiomyocyte contraction: Structure-activity relationships and stable analogues

17(R),18(S)-Epoxyeicosatetraenoic acid [17(R),18(S)-EETeTr], a cytochrome P450 epoxygenase metabolite of eicosapentaenoic acid (EPA), exerts negative chronotropic effects and protects neonatal rat cardiomyocytes against Ca 2+-overload with EC50 ? 1-2 nM. Structure-activity studies revealed that a cis-Delta11,12- or Delta14,15- olefin and a 17(R),18(S)-epoxide are minimal structural elements for antiarrhythmic activity whereas antagonist activity was often associated with the combination of a Delta14,15-olefin and a 17(S),18(R)-epoxide. Compared with natural material, the agonist and antagonist analogues are chemically and metabolically more robust and several show promise as templates for future development of clinical candidates.
