Ropinirole, a Non‐Ergoline Dopamine Agonist [PDF]
CNS Drug Reviews, 2005 ABSTRACTDopamine agonists have become indispensable in the treatment of Parkinson's disease. In every‐day practice, however, the decision to select the best compound for an individual patient is rendered difficult because of the large number of substances available on the market.

Alkylation of ergoline derivatives at position N(1)
, 1982 N(1)-Alkyl-8β-ergolines I-XII were prepared by alkylation of 8β-ergoline derivatives XIII to XVIII with alkyl halides in dimethyl sulphoxide in the presence of potassium hydroxide. The compounds I-XII exhibited weak inhibition effects on the secretion of

The Journal of Physiology, EarlyView.Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Preparation and Use of Nitrogen- or Sulfur Containing Heterocycles in Organic Synthesis
, 1980 The utility of intramolecular cycloadditions of ortho-quinodimethanes for the synthesis of complex polycyclic molecules is illustrated: 1) by the stereoselective synthesis of the natural alkaloid (±)-chelidonine starting from a benzocyclobutene; 2) by ...

The Journal of Physiology, EarlyView.Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

Pleuropulmonary changes induced by ergoline drugs [PDF]
European Respiratory Journal, 1996 Classic ergolines, such as bromocriptine, methysergide and ergotamine, can induce chronic pleuropneumonitis. We present the cases of eight patients who developed similar changes whilst on other ergolines. In this retrospective case study spanning 1985-1995, clinical data, radiological material, pulmonary function, bronchoalveolar lavage and ...

, 2007 A new method for the oxidation of ergoline alcohols to aldehydes was found (TFFA-DMSO, -78 °C, then DIPEA). Structural features of ergolines required for successful C7-C8 double bond introduction via Polonovski-Potier reaction of respective 6-N-oxides ...

The total syntheses of ring -A substituted ergolines
, 1998 Three types of ergolines, having a substituent in ring A were designed and their total syntheses were attempted. N-substituted 12-methoxyergolines were synthesized as potential serotonergic agents to test the hypothesis of bioisosterism between the C8 ...
