Why Do Chemically Similar Pharmaceutical Molecules Crystallize in Different Structures: A Case of Droperidol and Benperidol [PDF]

open access: closedCrystal Growth & Design, 2016
A detailed study of molecular conformation and intermolecular interactions in the experimental crystal structures and general trends observed in the Cambridge Structural Database as well as theoretical calculations were performed to identify the reason for the formation of different crystal structures of two chemically very similar pharmaceutical ...

Radiation dosimetry of [18F] (N-methyl)benperidol as determined by whole-body PET imaging of primates.

open access: closedNuclear Medicine and Biology, 1997
Radiation absorbed doses due to IV administration of [18F](N-methyl) benperidol ([18F]NMB) were estimated by whole-body PET imaging of nonhuman primates. Time-activity curves were obtained for nine compartments (striatum, eyes, heart, lungs, liver, gallbladder, intestines, kidneys, bladder) by using dynamic PET scans of three different baboons given ...

Ultraviolet spectrophotometry for the determination of benperidol by a difference procedure and for the elucidation of its polymorphic structures.

open access: closedThe Analyst, 1986
Benperidol contains two chromophores separated by a non-conjugated system. Its ultraviolet absorption spectrum, in acidic or neutral aqueous solution, shows maxima due to the p-fluoroacetophenone chromophore (at 249 nm) and to the benzimidazolone chromophore (at 232 and 279 nm).

Polymorphism and possible intramolecular bonding in benperidol

open access: closedInternational Journal of Pharmaceutics, 1986
Abstract The existence of two polymorphs and two solvates of benperidol has been confirmed by IR spectrophotometry and differential scanning calorimetry, but an amorphous form and a possible third polymorph have been shown to be mixtures of the other two polymorphs.

The control of deviant sexual behavior by drugs: A double-blind controlled study of benperidol, chlorpromazine, and placebo

open access: closedArchives of Sexual Behavior, 1974
A method for assessing the effect of drugs on sexual drive and arousability has been developed and used to compare the effect of a butyrephenone, benperidol, with chlorpromazine and placebo. Measures of change used included sexual behavior ratings, self-ratings of frequency of sexual thoughts, semantic differential ratings, and penile erections to ...

Benperidol - a drug for sexual offenders?

open access: closedDrug and Therapeutics Bulletin, 1974
Benperidol (Anquil - Janssen) is a butyrophenone which the makers claim ‘removes the desire to indulge in antisocial forms of sexual behaviour but the ability to function appropriately in the normal sexual environment may be retained’. It is structurally similar to haloperidol (Serenace - Searle) and trifluperidol (Triperidol - Janssen), both of which ...

Radiosynthesis of (N-[11C]methyl)benperidol for PET investigation of D2 receptor binding

open access: closedRadiochimica Acta, 2004
Abstract A procedure for the reliable production of the novel PET D2 receptor ligand (N-[11C]methyl)benperidol ([11C]NMB) is described. The method is based on N-methylation of benperidol using [11C]methyl iodide from the PETtrace MeI MicroLab, with product purification via normal-phase HPLC.
