Molecular Mind Games: The Medicinal Action of Cyclodextrins in Neurodegenerative Diseases

Cyclodextrins are often used as molecular carriers for small active ingredients in the medicine. Recently, the intrinsic medicinal activity of some of these compounds has been under investigation, mainly related to their ability to interfere with cholesterol and, therefore, prevent and treat cholesterol-related diseases such as cardiovascular disease and neuronal diseases arising from altered cholesterol and lipid metabolism. One of the most promising compounds within the cyclodextrin family is 2-hydroxypropyl-β-cyclodextrin (HPβCD), owing to its superior biocompatibility profile. This work presents the most recent advances in the research and clinical use of HPβCD against Niemann–Pick disease, a congenital condition involving cholesterol accumulation inside lysosomes in brain cells, Alzheimer’s and Parkinson’s. HPβCD plays a complex role in each of these ailments, going beyond the mere sequestering of cholesterol molecules and involving an overall regulation of protein expression that helps restore the normal functioning of the organism.

IgG N-Glycosylation Is Altered in Coronary Artery Disease

Coronary artery disease (CAD) is the most common cardiovascular disease, and previous studies have shown a significant association between N-glycosylation and the development of atherosclerotic plaques. Genos LtdSveučilište u Rijeci / University of Rijeka and University of Zagreb/Sveuciliste u Zagrebu teamed up to determine whether the N-glycome of immunoglobulin G is associated with the disease as N-glycans are known to alter the effector functions of IgG, which may enhance the inflammatory response.
The most notable differences were observed in women, where the presence of sialylated N-glycan structures was negatively associated with CAD. The obtained data provide insight into the IgG N-glycome composition in CAD as well as the biomarker potential of IgG N-glycans in CAD.

Disease management to disease modification – removing plaque to undo atherosclerosis

You can read a great interview with folks from Cyclarity Therapeutics at Longevity.Technology. Since they are one of the few companies developing tailor-made CDs to tackle a major disease, this is certainly worth attention.
“Cyclarity’s approach to true disease medication, and therefore reversal of age-related disease, without doubt, offers a great deal of promise for investors, for healthcare systems in the US and globally, and most of all for those affected by the atherosclerosis-related disease.
. . . this may be the perfect opportunity for Cyclarity to enter the field, as it is one of the few solutions available that addresses the limiting factors of previous therapies both from a scientific perspective and from a market perspective.”

Beren Awarded Expedited Roadmap for Treatment of Homozygous Familial Hypercholesterolemia

Fascinating news from Beren Therapeutics:
Beren Awarded Expedited Roadmap for Treatment of Homozygous Familial Hypercholesterolemia
Beren’s novel lead asset, BRN-002, was awarded an Innovation Passport under the United Kingdom’s Innovative Licensing and Access Pathway (ILAP), for the reversal of atherosclerosis in patients with Homozygous Familial Hypercholesterolemia. The ILAP aims to accelerate the time to market for innovative medicines that address the needs of patients with life-threatening or seriously debilitating diseases.
“We are excited to begin work under ILAP and look forward to collaborating with other regulators, payors, and governments to expedite the development and identify and remove access barriers.” – commented Jason Camm, CEO. Jules Payne from HEART UK – The Cholesterol Charity added that “Significant unmet needs remain, and with this advancement, we are hopeful for a new treatment option that can truly alter the course of the disease for the children and patients living with HoFH.”
Beren Therapeutics, P.B.C. is currently in stealth.

Cyclodextrin boostered-high density lipoprotein for antiatherosclerosis by regulating cholesterol efflux and efferocytosis

The cyclodextrin-supported atherosclerosis treatment field is getting crowded. Here is a unique approach using polyethylene glycol succinate (TPGS)-CD, which was adsorbed on rHDL, then modified with Apo-Ai, and coated with hyaluronan to obtain HT-rHDL. Piece of cake!
