Synthesis of 2-(1,5-diaryl-1,4-pentadien-3-ylidene)-hydrazinecarboximidamide hydrochloride catalyzed by p-dodecylbenzenesulfonic acid in aqueous media under ultrasound irradiation
Ultrason Sonochem 2012 Sep;19(5):1033-8.PMID:22440718DOI:10.1016/j.ultsonch.2012.02.009.
Amidinohydrazone compounds are very important synthetic intermediates and can serve as versatile precursors in synthesis of many natural products and drug molecules. The use of ultrasound, p-dodecylbenzenesulfonic acid (DBSA) and water as solvent improved the synthesis of different 2-(1,5-diaryl-1,4-pentadien-3-ylidene)-hydrazinecarboximidamide hydrochlorides. The best reaction conditions for the condensation of 1,5-diphenyl-1,4-pentadien-3-one with aminoguanidine hydrochloride were as follows: 1,5-diphenyl-1,4-pentadiene-3-one (1, 1 mmol), aminoguanidine hydrochloride (1.1 mmol), DBSA (0.5 mmol), water 10 mL, reaction temperature 25-27°C, irradiation frequency 25 kHz. 2a was achieved in 94% yield within 2h. The other seven amidinohydrazones were obtained in 84-94% yield within 2-3h under the same conditions. Compared to the method involving catalysis by hydrochloric acid in refluxing EtOH, the advantages of present procedure are milder conditions, shorter reaction times, higher yields, and environmental friendly conditions, which make it a useful strategy for the synthesis of analogues.
P-Trifluoromethyl ligands derived from Josiphos in the Ir-catalysed hydrogenation of 3,4-dihydroisoquinoline hydrochlorides
Dalton Trans 2015 Dec 7;44(45):19566-75.PMID:26161502DOI:10.1039/c5dt02019k.
The synthesis of mono P-trifluoromethyl and therefore P-stereogenic Xyliphos-derived ligands 5 and their application in the Ir-catalyzed enantioselective hydrogenation of 1-substituted 3,4-dihydroisoquinolinium species (DHIQ) are reported. The ligands were prepared following previous procedures involving the reaction of a bistrifluoromethylphosphine with lithiated (R)-Ugi amine 1. Chloroiridium(i) cyclooctadiene precatalysts containing these new partially electron-poor ligands 9 were found to be poorly active in the hydrogenation of free 1-phenyl-3,4-dihydroisoquinoline 12a. However, the corresponding hydrochloride 12a·HCl was smoothly reduced at 55-60 °C and 100 bar hydrogen pressure. The (SP)-configured ligand (SP)-5 yielded significantly higher enantioselectivity in hydrogenation experiments than its P-stereoisomeric counterpart (RP)-5. These new ligands were subsequently applied in the hydrogenation of a series of different 1-substituted 3,4-DHIQ chlorides 12a-l·HCl. Good to excellent enantioselectivity was observed for substrates bearing relatively large substituents in position 1, reaching 96% ee for 1-Ph-DHIQ chloride 12a·HCl without the help of any additives. Furthermore, an interesting counter ion effect was found with chloride being the best and hexafluorophosphate being very detrimental to enantioselectivity.
1-[4-(2-Dimethylaminoethoxy)phenylcarbonyl]-3,5-Bis(3,4,5-Trimethoxybenzylidene)- 4-Piperidone hydrochloride and Related Compounds: Potent Cytotoxins Demonstrate Greater Toxicity to Neoplasms than Non- Malignant Cells
Med Chem 2022;18(9):1001-1012.PMID:35319387DOI:10.2174/1573406418666220322154110.
Background: The incidence of cancer has been increasing worldwide. Unfortunately, the drugs used in cancer chemotherapy are toxic to both neoplasms and normal tissues, while many available medications have low potencies. Conjugated α,β-unsaturated ketones differ structurally from contemporary anticancer medications , some of which have noteworthy antineoplastic properties. Objectives: This study aimed to design and synthesize highly potent cytotoxins with far greater toxicity to neoplasms than to non-malignant cells. Methods: A series of N-acyl-3,5-bis(benzylidene)-4-piperidone hydrochlorides 4a-n were prepared and evaluated against Ca9-22, HSC-2, HSC-3, and HSC-4 squamous cell carcinomas as well as against HGF, HPLF, and HPC non-malignant cells. QSAR and western blot analyses were performed. Results: The majority of compounds display submicromolar CC50 values towards the neoplasms; the figures for some of the compounds are below 10-7 M. In general, 4a-n have much lower CC50 values than those of melphalan, 5-fluorouracil, and methotrexate, while some compounds are equitoxic with doxorubicin. The compounds are far less toxic to the non-malignant cells, giving rise to substantial selectivity index (SI) figures. A QSAR study revealed that both potency and the SI data were controlled to a large extent by the electronic properties of the substituents in the arylidene aryl rings. Two representative compounds, 4f and 4g, caused apoptosis in HSC-2 cells. Conclusion: The compounds in series 4 are potent cytotoxins displaying tumor-selective toxicity. In particular, 4g with an average CC50 value of 0.04 μM towards four malignant cell lines and a selectivity index of 46.3 is clearly a lead molecule that should be further evaluated.
Green Formation of Novel Pyridinyltriazole-Salicylidene Schiff Bases
Curr Org Synth 2019;16(2):309-313.PMID:31975681DOI:10.2174/1570179416666181207145951.
Aim and objective: In this work, water was used as solvent for the eco-friendly synthesis of imines under microwave irradiation. In the first step of the study, 5-pyridinyl-3-amino-1,2,4-triazole hydrochlorides were synthesized in the reaction of amino guanidine hydrochloride with different pyridine carboxylic acids under acid catalysis. A green method for 5-pyridinyl-3-amino-1,2,4-triazoles was developed with the assistance of microwave synthesis. In the second step, the eco-friendly synthesis of imines was achieved by reacting 5- pyridinyl-2H-1,2,4-triazol-3-amine hydrochlorides with salicylic aldehyde derivatives to produce 2-(5- pyridinyl-2H-1,2,4-triazol-3-ylimino)methyl)phenol imines. Materials and methods: Microwave experiments were done using a monomode Anton Paar Monowave 300 microwave reactor (2.45 GHz). Reaction temperatures were monitored by an IR sensor. Microwave experiments were carried out in sealed microwave process vials G10 with maximum reaction volume of 10 mL. Results: When alternative methods were used, it was impossible to obtain good yields from ethanol. Nevertheless, the use of water was successful for this reaction. After 1-h microwave irritation, a yellow solid was obtained in 82% yield. Conclusion: In this work an eco-friendly protocol for the synthesis of Schiff bases from 5-(pyridin-2-, 3- or 4- yl)-3-amino-1,2,4-triazoles and substituted salicylic aldehydes in water under microwave irradiation was developed. Under the found conditions the high yields for the products were achieved at short reaction time and with an easy isolation procedure.

Toxicol Int 2013 Sep;20(3):268-74.PMID:24403737DOI:10.4103/0971-6580.121680.
Background: Mannich bases are an important class of compounds in medicinal chemistry with a wide spectrum of biological activities, however, knowledge on their toxicity is limited. Materials and methods: Two Mannich base hydrochlorides 1a (2-thienyl-β-dimethylaminoethyl ketone hydrochloride) and 1b (β-dimethylaminopropiophenone hydrochloride) were synthesized and characterized on the basis of their infrared and nuclear magnetic resonance spectral data. The potential effects of the synthesized compounds (5 mg/kg, i.p, during 30 days) on relative weight, hematological parameters, biochemical parameters, and neurotoxicity were tested using male Wistar rat. Results: The results showed that compound 1b alters body weight on the first 10 days (182%, P < 0.01) and on the last 10 days (107%, P < 0.01) of treatment. The same treatment decreases food intake (P < 0.01) and increases water intake (P < 0.05). Both compounds induced a deficit on rotarod test manifested by a decrease of grasping time (1a: 65.33%, P < 0.01; 1b: 60.55%, P < 0.01) and fall time (1a: 59.75%, P < 0.01; 1b: 56.81%, P < 0.01) only on the last day of training. Moreover, Mannich base 1b decreases the liver relative weight (22.24%, P < 0.01). It was also observed that both products decrease the total serum cholesterol (Ch) levels (1a: 52.87%, P < 0.01; 1b: 64.70%, P < 0.01). Interestingly, compounds 1a and 1b affect hematological parameters manifested by an increase of the number of white blood cells (1a: 32.29%, P < 0.05; 1b: 20.64%, P < 0.05) and red blood cells (RBCs) (1a: 12.57%, P < 0.05; 1b: 20.11%, P < 0.05), an increase of red cell hemoglobin concentration (1a: 10.48%, P < 0.05; 1b: 16.12%, P < 0.05) and of the volume occupied by RBCs or hematocrit (1a: 18.28%, P < 0.05; 1b: 15.56%, P < 0.05), and an increase of the number of platelets (1a: 16.80%, P < 0.05; 1b: 39.96%, P < 0.05) accompanied by a decrease in hemoglobin level only with the compound 1a (7.41%, P < 0.05). Conclusion: These results show that both compounds 1a and 1b induced a hypoxia status associated to low level of Ch and liver toxicity. The deficit observed by rotarod could be explained by the myorelaxant effect of the used products.
