Synthesis, anticholinesterase activity and molecular modeling studies of novel carvacrol-substituted amide derivatives

In the present study, 23 novel carvacrol derivatives involving the amide moiety as a linker between the alkyl chains and/or the heterocycle nucleus were synthesized and tested in vitro as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhib

Synthesis and biological evaluation of carvacrol-based derivatives as dual inhibitors of H. Pylori strains and ags cell proliferation

This study reports on the synthesis, structural assessment, microbiological screening against several strains of H. pylori and antiproliferative activity against human gastric adenocarcinoma (AGS) cells of a large series of carvacrol-based compounds. Structural analyses consisted of elemental analysis,1 H/13 C/19 F NMR spectra and crystallographic studies. The structure-activity relationships evidenced that among ether derivatives the substitution with specific electron-withdrawing groups (CF3 and NO2) especially in the para position of the benzyl ring led to an improvement of the antimicrobial activity, whereas electron-donating groups on the benzyl ring and ethereal alkyl chains were not tolerated with respect to the parent compound (MIC/MBC = 64/64 μg/mL). Ester derivatives (coumarin-carvacrol hybrids) displayed a slight enhancement of the inhibitory activity up to MIC values of 8–16 μg/mL. The most interesting compounds exhibiting the lowest MIC/MBC activity against H. pylori (among others, compounds 16 and 39 endowed with MIC/MBC values ranging between 2/2 to 32/32 μg/mL against all the evaluated strains) were also assayed for their ability to reduce AGS cell growth with respect to 5-Fluorouracil. Some derivatives can be regarded as new lead compounds able to reduce H. pylori growth and to counteract the proliferation of AGS cells, both contributing to the occurrence of gastric cancer.

Betulin-derived compounds as inhibitors of alphavirus replication

This paper describes inhibition of Semliki Forest virus (SFV) replication by synthetic derivatives of naturally occurring triterpenoid betulin (1). Chemical modifications were made to OH groups at C-3 and C-28 and to the C-20-C-29 double bond. A set of heterocyclic betulin derivatives was also assayed. A free or acetylated OH group at C-3 was identified as an important structural contributor for anti-SFV activity, 3,28-di-O-acetylbetulin (4) being the most potent derivative (IC50 value 9.1 μM). Betulinic acid (13), 28-O-tetrahydropyranylbetulin (17), and a triazolidine derivative (41) were also shown to inhibit Sindbis virus, with IC50 values of 0.5, 1.9, and 6.1 μM, respectively. The latter three compounds also had significant synergistic effects against SFV when combined with 3′-amino-3′-deoxyadenosine. In contrast to previous work on other viruses, the antiviral activity of 13 was mapped to take place in virus replication phase. The efficacy was also shown to be independent of external guanosine supplementation.

Solid-supported synthesis of bio-active carvacrol compounds using microwaves

The most abundant and potent natural products having a broad spectrum of biological activity against various pests are terpenoids, especially monoterpenoids. The chemical modification of natural monoterpenoids has been reported to result in modified biological activity. The present work emphasizes the structural modification of carvacrol, a phenolic monoterpenoid, through the synthesis of different ether and ester derivatives that are useful for structure-activity relationship studies to exploit the potent molecules. The carvacrol was reacted with alkyl halides and acid chlorides under microwaves using solid supports such as silica gel, alumina, and fly ash to give ethers and esters, respectively. The synthesis of dimeric ether and ester compounds using dihalides and acid dichlorides was conducted with novel reactions. Additional features of the methodology include very fast reactions, higher yields and purities of the products, and an ecofriendly approach. Copyright Taylor & Francis Group, LLC.

Synthesis of biologically active carvacrol compounds using different solvents and supports

Natural monoterpenoids have been documented for their acute toxicity and repellent, antifeedent, reproduction inhibitory, and insecticidal actions. The present work aims to derive a variety of ether and ester compounds using polymer-supported reactions from the polymer-supported carvacrol anion was reacted with alkyl halides and acid chlorides to afford carvacryl ethers and esters, respectively. Furthermore, a special study on the effect of different solvents and supports revealed that Amberlite IRA 400 (chloride form) was found to be the best polymer support and acetone among the solvents.

Solvent-free synthesis of substituted phenoxyacetic acids under microwave irradiation

A comparison of microwave-activated vs. classical organic synthesis is presented for a variety of growth-regulator compounds with a phenoxyacetic acid structure. Microwave-assisted nucleophilic substitutions are safely and conveniently carried out in an open vessel, without any solvent. Yields are very good, and reaction times are extremely short.
