Physicochemical and structural analysis of N-phenylacetyl-L-prolylglycine ethyl ester (Noopept) - An active pharmaceutical ingredient with nootropic activity.

N-Phenylacetyl-L-prolylglycine ethyl ester (Noopept, GVS-111, omberacetam) is an orally available active pharmaceutical ingredient (API), with neuroprotective properties and ability to enhance cognitive function. It belongs to nootropic family of drugs and is included in the group of racetams, although its chemical structure is quite different than the other compounds from this group, including the most popular one - piracetam. The mechanism of action of this API is multifaced and is considered to be involving modulation of various neurotransmitter systems within the brain.

A Review on Cyclodextrins/Estrogens Inclusion Complexes.

This review focuses on the methods of preparation and biological, physiochemical, and theoretical analysis of the inclusion complexes formed between estrogens and cyclodextrins (CDs). Because estrogens have a low polarity, they can interact with some cyclodextrins' hydrophobic cavities to create inclusion complexes, if their geometric properties are compatible. For the last forty years, estrogen-CD complexes have been widely applied in several fields for various objectives.

Efficacy and safety of liraglutide compared to sulphonylurea during Ramadan in patients with type 2 diabetes (LIRA-Ramadan): a randomized trial.

Aims: Compare effects of liraglutide 1.8 mg and sulphonylurea, both combined with metformin, on glycaemic control in patients with type 2 diabetes (T2D) fasting during Ramadan.

Materials And Methods: In this up to 33-week, open-label, active-controlled, parallel-group trial, adults [glycated haemoglobin (HbA1c) 7%-10% (53-86 mmol/mol); body mass index ≥20 kg/m(2) ; intent to fast] were randomized (1:1) ≥10 weeks before Ramadan to either switch to once-daily liraglutide (final dose 1.
