Descripción general

(2-Hydroxypropyl)-γ-cyclodextrin belongs to the class of cyclodextrin derivatives, which exhibit a greater extent of solubility in water compared to their parent compounds. It is widely used in parenteral formulations and solid dosage forms to aid in the improvement of their stability, dissolution, bioavailability, etc.

Aplicación

(2-Hydroxypropyl)-γ-cyclodextrin may be used:
  • As a mobile phase additive in the study of the host-guest interaction with organic low molecular mass compounds prior to their quantification using reversed phase-high performance liquid chromatography (RP-HPLC) technique.
  • As a chiral surfactant for the analysis of econazole by micellar electrokinetic chromatography (MEKC).
  • As an analytical standard for the determination of the analyte in biological samples by HPLC.
  • As a chiral selector for the identification of propiconazole by MEKC.

The orexin/hypocretin system has recently been implicated in reward-processing and addiction. We examined the involvement of the orexin system in cue-induced reinstatement of extinguished cocaine-seeking by administering the orexin 1 receptor antagonist SB-334867 (SB) or the orexin 2 receptor antagonist

When given in a warm environment MDMA (3,4-methylenedioxymethamphetamine, ecstasy) causes hyperthermia by increasing interscapular brown adipose tissue (iBAT) heat production and decreasing heat loss via cutaneous vasoconstriction. When given in a cold environment, however, MDMA causes hypothermia by an unknown
