Liposome Enhanced Detection of Amyloid Protein Aggregates
Kocsis, Istvan,Sanna, Elena,Hunter, Christopher A.
, p. 647 - 650 (2021)
Thioflavin-T is used to image amyloid aggregates because of the excellent turn-on fluorescence properties, but binding affinities are low. By mounting multiple dye units on the surface of a vesicle, the binding affinity for α-synuclein fibrils is increased by three orders of magnitude, and the optical response is increased. Cooperative interactions of the dye headgroup and lipid with the protein provide a general strategy for the construction of multivalent amyloid probes based on vesicles.
Synthesis of alkyl [(alkyl 6-deoxy-alpha-D-gluco-heptopyranosyl- uronate) 6-deoxy-alpha-D-gluco-heptopyranosid]uronates, a novel type of mirror pseudo cord factor.
Baer,Breton
, p. 181 - 189 (1991)
The 1-octyl, 1-pentadecyl, 1-hexadecyl, 1-heptadecyl, and 1-octadecyl diesters of (6-deoxy-alpha-D-gluco-heptopyranosyluronic acid) 6-deoxy-alpha-D-gluco-heptopyranosiduronic acid, a new homolog of trehalosuronic acid, were prepared by two procedures. One procedure involved conversion of the peracetylated acid into its dichloride, reaction of the latter with the alkanols, and acid-catalyzed deacetylation of the products, whereas the other consisted of reaction of alkyl mesylates with the potassium salt of the unprotected acid.

Alkylglycerols (AKGs) are bioactive natural compounds that vary by alkyl chain length and degree of unsaturation, and their absolute configuration is 2S. Three AKGs (5l–5n) were synthesised in enantiomerically pure form, and were characterised for the first time together with 12 other known and naturally occurring AKGs (5a–5k, 5o). Their structures were established using 1H and 13C APT NMR with 2D-NMR, ESI-MS or HRESI-MS and optical rotation data, and they were tested for their antibacterial and antibiofilm activities. AKGs 5a–5m and 5o showed activity against five clinical isolates and P. aeruginosa ATCC 15442, with MIC values in the range of 15–125 μg/mL. In addition, at half of the MIC, most of the AKGs reduced S. aureus biofilm formation in the range of 23%–99% and P. aeruginosa ATCC 15442 biofilm formation in the range of 14%–64%. The antibiofilm activity of the AKGs assessed in this work had not previously been studied.

scheme or table, p. 233 - 235 (2010/12/20)
In this work, a number of lipidic amino alcohols wereas synthesized and evaluated in vitro on cultures of Leishmania amazonensis and Leishmania chagasi. Nine amino alcohols showed inhibition of L. chagasi growth, and seven of them showed inhibition of L. amazonensis with IC50 below 10 μm. Compound 11f was more active than the reference drug amphotericin B against L. chagasi promastigote forms.

A series of N- and C-alkylated amino alcohols and of their protected galactopyranosyl derivatives was synthesized and evaluated for antitubercular activity. Five of these compounds displayed good activity, with a MIC below 12.5 μg/mL. The presence of the carbohydrate slightly affected the antibacterial activity.
