The synthesis of bile acid conjugates plays a significant role in pharmacology and organic chemistry. These complex compounds are widely studied due to their potential therapeutic applications (e.g., drug carriers or antibacterial agents) and their impact on interactions with biological target systems. It is important to determine the biological ac...
1,3,5-triazine derivatives are useful compounds with potential applications in various
branches of chemical industry, including pharmaceutical chemistry, cosmetic
chemistry, photochemistry, and organic chemistry. Due to the growing environmental
requirements on conducting efficient, economical, and safe syntheses, development of
new methods for syn...
Drug discovery is a challenging process, with many compounds failing to progress due to unmet pharmacokinetic criteria. Lipophilicity is an important physicochemical parameter that affects various pharmacokinetic processes, including absorption, metabolism, and excretion. This study evaluated the lipophilic properties of a library of ipsapirone der...
Six steroid conjugates of bile acids and sterol derivatives have been synthesized using the click chemistry method. The azide-alkyne Huisgen cycloaddition of the propionyl ester of lithocholic, deoxycholic and cholic acid with azide derivatives of cholesterol and cholestanol gave new bile acid-sterol conjugates linked with a 1,2,3-triazole ring. Pr...
New derivatives of the known antipsychotic drug olanzapine have been obtained as potential compounds with anticancer activity in two metabolically different breast cancer cell lines: MCF-7 and triple negative MDA-MB-231. The compounds were obtained under phase transfer catalysis (PTC) in the presence of microwave irradiation (MW) or ultrasound ("))...
In this study, we have developed a new ultrasonic synthesis method of dibenzoepines using olanzapine and quetiapine, which are well-known drugs for the treatment of schizophrenia and bipolar disorder. The method is based on the N-alkylation reaction of the piperazine fragment in tricyclic compounds with methyl iodide or 2-(2-chloroethoxy)ethanol as...
Considering the key functions of the 5-HT 7 receptor, especially in psychiatry, and the fact that effective and selective 5-HT 7 receptor ligands are yet to be available, in this work, we designed and synthesized novel 1,3,5-triazine derivatives particularly based on the evaluation of the effect of substituents at aromatic rings on biological activ...
In our research to find new dual 5-HT1A/5-HT7 ligands from the long-chain arylpiperazine (LCAP) family, we applied a new synthesis method with the support of ultrasound. The first tests related to the synthesis were carried out on the preparation of approved drugs with arylpiperazine structures such as aripiprazole, trazodone and flibanserin . The...
New six steroid conjugates have been prepared from bile acids (tail part)and sterol (head part) derivatives using click chemistry method. The azide-alkyne Huisgen cycloaddition (intermolecular 1,3-dipolar cycloaddition) of the azide derivatives of lithocholic, deoxycholic, cholic acid and propiolate ester of cholesterol and cholestanol gave a new b...
Phase transfer catalysis (PTC) is an excellent possibility in the synthesis of organic compounds as it allows the reactions to be carried out under the conditions of green chemistry, while maintaining high yields and selectivity. The great advantage of these reactions is also the possibility of carrying out the reactions not only under conventional...
Owing to their multifunctional pharmacological profiles (including dual 5-HT1A/5-HT7 action), arylpiperazine derivatives are widely used for treating central nervous system diseases including the depression or neuropathic pain. Herein we describe the design, synthesis and evaluation of biological activity of novel 5-HT7 ligands derived of 2,4,6-tri...
Schizophrenia and depression are diseases that significantly impede human functioning in society. Current antidepressant drugs are not fully effective. According to literature data, the effect on D2R or
5-HT1AR can effectively reduce the symptoms of depression or schizophrenia. Recent research hypothetized that the synergism of both of these recept...
Developing new and selective 5-HT7R ligands may have a key impact on the treatment of central nervous system diseases including depression. We have found that indoleaminotriazine core fused with alkyl aryl moiety exhibits high affinity and selectivity to 5-HT7R. SAR analysis demonstrated that the ethyl or ethoxy group (5c 5-HT7R Ki=8 nM; 5d 5-HT7R...
The currently applied synthetic methods of serotonin receptor ligands belonging to the group of long-chain arylpiperazines, including ipsapirone, require the use of toxic solvents as well as comprise of numerous synthetic steps. Moreover, the reaction yield does not exceed 60% in the majority of cases. These factors lead to an increased energy cons...
A B S T R A C T Aripiprazole is a widely used antipsychotic approved by the FDA (Food and Drug Administration) in 2002. Methods for preparation of aripiprazole mainly involve the use of expensive and toxic solvents, and the reaction time can be even several hours long. Our method allows to obtain aripiprazole with a yield of approximately 70–80% ov...
Aripiprazole is a widely used antipsychotic approved by the FDA (Food and Drug Administration) in 2002. Methods for preparation of aripiprazole mainly involve the use of expensive and toxic solvents, and the reaction time can be even several hours long. Our method allows to obtain aripiprazole with a yield of approximately 70–80% over just a few mi...

Does anyone know, who or which institution offers MTDH screening panel for a new small-molecules?! I would be grateful for an answer.
I have question about building 3DQSAR model via regression model. I cant achieve r^2 more than 0.6 for 'test set' as well as for 'training CV'-what is this?. I am wondering whether 'training set' should be as similar to each others as its possible and use 'reference cmpd' belonging to the 'training set'? Or 'reference set' may be different compound - not similar to training compounds but active.
Hello
I would like to ask how to calculate CNS MPO. I know that its a sum of 6 values (ClogP, ClogD, MW, HBD and pKa - expressed in monotonic decreasing transformation (T0), and TPSA - expressed in hump function transformation (T0)). I can calculate typical values eg in Chemaxon but how to do transformation? Is there needed any software or sth like that?
Thank You in advance.
To build this homology model, I used 5-HT1B receptor as a template. And I need this info to set up a grid box in autodock.
