20 With a preference for lipids, cell lysis begins to occur at 3 Г— 10 в€’5 M. 23 The critical micelle concentration of CPZ in water is about 10 в€’5 M. 20вЂ“22 For example, similar activity has been noted for alamethacin, which forms micelles in aqueous solutions and readily incorporates into plasma bilayers, forming channels by self-association. 18,19 Such amphipaths distribute into rich and poor domains in phospholipid (PL) multilayers. 17 The notion that the PTH accumulates in membranes heterogeneously is well-established. 14вЂ“16 Goosey and Doggett pointed out that PTH neuroleptics involve lipophilicity rather than solely shape-specific mechanisms. After all, micro-organisms have none of the above-mentioned receptors yet become вЂњsedatedвЂќ or otherwise react to PTH medicinal intervention. 13 A truism exists that the longer a drug is in use, the more side-effects are discovered. 9вЂ“12 Human toxicity, often a concern with PTHs, can be measured in vitro using 3D cultures, which accurately reflect the in vivo response. 1,5,7,8 PTH, as neuroleptics, involve stereospecific sites, but their mode of action includes so-called вЂњnon-neuronalвЂќ interactions that may cover many side-effects and contribute to other psychotropic and/or biological activity. 1вЂ“6 Evidence is mounting that alone or as helper compounds, they may revive the use of older, classical antibiotics to combat the alarming rise of multi-resistant microbes world-wide. 1A for representatives) have shown therapeutic effectiveness against deleterious micro-organisms and cancer cells. Introduction Chlorpromazine hydrochloride (CPZ) and related exobiotic, amphipathic, micelle-forming phenothiazine (PTH) salts (see Fig. These observations may open new opportunities for the development of novel therapies.

PL adduct has a вЂњhelical shapeвЂќ showing Fibonacci properties for molecules.In summary, the reproducibility and similarity of the measurements using different PTH derivatives and PL suggests that similar adducts are formed in all the cases. The of the PTH/PL was always larger than that of the self-associated pure PTH. The same order was found when hydrogen ion concentration was increased when plotted against the MR for each separate diacyl series.

The MR of Series 2 followed the PL order PC < PG < PS < PE < PA, echoing the changes in the membrane proportions found in eukaryotic cells proceeding from the plasma membrane to the endoplasmic reticulum. вЂSeries 2вЂ™ followed the lipophilicity of PL and could be related to various non-neuronal physiological aspects. вЂSeries 1вЂ™ (PMTZ < PMZ < CPZ < PClP < TFP) followed the ionization potential and concomitant sedative effects. We observed water soluble products with replicable molar ratios (MR) that could be divided into two series.

HCl), prochlorperazineв™ІHC1 (PClPв™ІHCl), trifluoperazineв™ІHCl (TFPв™ІHCl) and synthetic 1,2diacyl- sn-glycero-3-phospholipids (PL) with even-numbered symmetric saturated diacyl chains with the headgroups choline (PC), glycerol (PG), serine (PS), ethanolamine (PE), phosphatidic acid (PA).

Micro-gravimetric titrations were performed on aqueous suspensions of promethazine (PMTZ), promazine (PMZ), triflupromazine (TFM), chlorpromazine (CPZ), prochlorperazine Here, we explore the spatial interaction of selected therapeutic phenothiazine hydrochloride derivatives (PTH) with various lipids. The fact that non-antibiotics can sensitise microorganisms for antibiotic treatment suggests that these molecules have valuable potential to treat multiple drug resistance.
