  Self-assembling properties of 6-O-alkyltrehaloses under aqueous conditions

  摘要：

  In this study, we report the self-assembling properties of 6-O-alkyltrehaloses with different chain lengths, that is, octyl, decyl, dodecyl, tetradecyl, and hexadecyl, under aqueous conditions. The materials were synthesized from trehalose via five reaction steps. The scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), and dynamic light scattering (DLS) measurements indicated that the self-assembling property of 6-O-dodecyltrehalose was completely different from that of the other derivatives. The former primarily formed spherical micelles in water, which further assembled into face-centered cubic-based aggregates when dried. The latter derivatives, on the other hand, formed vesicle-type particles via the formation of lamellar-like planes, which further merged with each other, most likely by the fusion of the planes, to construct larger aggregates.

  Synthesis of trehalose-based compounds and their inhibitory activities against Mycobacterium smegmatis

  摘要：

  The synthesis of a library of trehalose-based compounds has been accomplished, and their activities against mycobacterium smegmatis have been determined. A preliminary structure-activity relationship (SAR) is reported. Despite not having a potent lead, one of the trehalose derivatives displays strong activity when applied with isoniazid (INH), which is known to have low sterilizing activity. The bacteriocidal nature of our compounds against Mycobacterium may be significant for the development of new therapies against tuberculosis. (C) 2004 Elsevier Ltd. All rights reserved.
