AbstractThe present paper deals with the evaluation of the stereoselective binding of antihistamines (brompheniramine, chlorpheniramine, hydroxyzine, orphenadrine and phenindamine), phenothiazines (promethazine and trimeprazine) and a local anesthetic (bupivacaine) to human plasma proteins. Since all of them are drugs highly bound to proteins, a methodology to determine the bound fraction of each drug enantiomer was proposed. This methodology includes the incubation of samples containing plasma and racemic drug, ultrafiltration of the mixture and the chiral separation of enantiomers in the bound drug fraction using affinity EKC (AEKC)‐partial filling technique and HSA as chiral selector. The results shown in this paper represent the first evidence of the enantioselective binding of some antihistamines such as brompheniramine, hydroxyzine, orphenadrine and phenindamine and the phenothiazines, promethazine and trimeprazine, to human plasma proteins. The binding of phenindamine to plasma presented the highest enantioselectivity (ES) (ES = 2.5) followed by trimeprazine (ES = 1.5) and promethazine (ES = 1.4).

An important topic in the drug discovery and development process is the role of drug binding to plasma proteins. In this paper the characterization of the interaction between antihistamines (cationic drugs) towards human serum albumin (HSA) and alpha(1)-acid glycoprotein (AGP) under physiological conditions by capillary electrophoresis-frontal analysis is presented. Furthermore, the binding of these drugs to all plasma proteins is evaluated by using ultrafiltration and capillary electrophoresis. Antihistamines present a wide-ranging behaviour with respect to their affinities towards plasma proteins. Orphenadrine, phenindamine, tripelenamine and tripolidine principally bind to HSA; carbinoxamine, dimetindene and etintidine principally bind to AGP; brompheniramine, chlorpheniramine and ranitidine present an important binding to lipoproteins and/or globulins and finally, chlorcyclizine, cinarizine, cyclizine, doxylamine, hydroxyzine, perphenazine and terfenadine do not bind to lipoproteins and/or globulins but bind to HSA and AGP in different extension. The interaction of antihistamines with HSA is determined by the hydrophobicity (direct relationship) and the polar surface area (indirect relationship) of the compounds. The steric parameters and hydrogen bonding character of compounds seems to be related with the binding of antihistamines to AGP. The antihistamine-HSA affinity constants were evaluated and the K(1) values ranged from 7 x 10(2)M(-1) (for doxylamine) to 4 x 10(4)M(-1) (for phenindamine).

A new pharmacophoric model for the H1-antagonist binding site is derived which reveals that a simple atom to atom matching of compounds is not sufficient; in this model, interacting residues from the receptor need to be included. To obtain this model, the bioactive conformations of several (semi-)rigid classical histamine H1-receptor antagonists have been investigated (cyproheptadine, phenindamine, triprolidine, epinastine, mequitazine, IBF28145, and mianserine). In general, these antihistamines contain two aromatic rings and a basic nitrogen atom. A previously derived pharmacophoric model with the nitrogen position fixed relative to the two aromatic rings is now found not to be suitable for describing the H1-antagonist binding site. A procedure is described which allows for significant freedom in the position of the basic nitrogen of the histamine H1-antagonist. The area accessible to the basic nitrogen is confined to the region accessible to its counterion on the histamine H1-receptor, i.e., the carboxylate group of Asp116. The basic nitrogen is assumed to form an ionic hydrogen bond with this aspartic acid which C alpha- and C beta-carbons are fixed with respect to the protein backbone. Via this hydrogen bond, the direction of the acidic proton of the antagonist is taken into account. Within these computational procedures, an aspartic acid is coupled to the basic nitrogen of each H1-antagonist considered; the carboxylate group is connected to the positively charged nitrogen via geometric H-bonding restraints obtained from a thorough database search (CSD). Also to the basic nitrogen of the pharmacophore is coupled an aspartic acid (to yield our new template). In order to derive a model for the H1-antagonist binding site, the aromatic ring systems of the antagonists and template are matched according to a previously described procedure. Subsequently, the C alpha- and C beta-carbons of the aspartic acid coupled to the H1-antagonists are matched with those of the template in a procedure which allows the antagonist and the carboxylate group to adapt their conformation (and also their relative position) in order to optimize the overlap with the template. A six-point pharmacophoric model is derived which has stereoselective features and is furthermore able to distinguish between the so-called "cis"- and "trans"-rings mentioned in many (Q)SAR studies on H1-antagonists. Due to its stereoselectivity, the model is able to designate the absolute bioactive configuration of antihistamines such as phenindamine (S), epinastine (S), and IBF28145 (R). A further merit of this study is that a model is obtained which includes an amino acid from the receptor.(ABSTRACT TRUNCATED AT 400 WORDS)
