Choline Chloride-Urea Deep Eutectic Solvent/Cu-Mn Iminodiacetate Coordination Polymer as an Efficient Catalytic System for Synthesis of Morita-Baylis-Hillman Adducts with Antimicrobial Activity.

This work shows the synthesis of a series of Morita-Baylis-Hillman adducts from isatin derivatives via an efficient green approach involving the use of a new catalyst system, a mixture of copper-manganese iminodiacetate 1D coordination polymer (Cu/Mn-IDA) and choline chloride-urea deep eutectic solvent (ChCl/urea 1:2). The adducts were obtained in good to excellent yields (59-97%) with shorter reaction times. The results demonstrate for the first time the synergistic catalytic effect of the combination of deep eutectic solvent and coordination polymer on the Morita-Baylis-Hillman reactions.

Morita-Baylis-Hillman adduct 2-(3-hydroxy-1-methyl-2-oxoindolin-3-il) acrylonitrile (CISACN) ameliorates the pulmonary allergic inflammation in CARAS model by increasing IFN-γ/IL-4 ratio towards the Th1 immune response.

Combined allergic rhinitis and asthma syndrome (CARAS) is an airway-type 2 immune response with a profuse inflammatory process widely affecting the world population. Due to the compromise of quality of life and the lack of specific pharmacotherapy, the search for new molecules becomes relevant. This study aimed to evaluate the effectiveness of the Morita-Bailys-Hillman adduct (CISACN) treatment in the CARAS experimental model.

Morita-Baylis-Hillman adduct 2-(3-hydroxy-2-oxoindolin-3-yl)acrylonitrile (ISACN) modulates the inflammatory process during LPS-induced acute lung injury.

Background: Despite its homeostatic role, inflammation is involved in several pathologies, such as acute lung injury. Morita-Ballys-Hilman adducts (MBHA) are a group of synthetic molecules and present a wide range of biological activities, including anti-inflammatory action. Thus, this study aimed to assess whether ISACN, an MBHA, modulates inflammation during acute lung injury induced by lipopolysaccharide (LPS).

Biological Activities of Morita-Baylis-Hillman Adducts (MBHA).

Background: The Morita-Baylis-Hillman reaction (MBHR) is considered one of the most powerful and versatile methodologies used for carbon-carbon bond formation. The reaction is defined as the condensation between an electrophilic carbon sp² and the α position of an olefin, carrying an electron-withdrawing group, in the presence of a catalyst. The advantages of the reaction are the high atom economy and mild reaction conditions.

Morita-Baylis-Hillman Adduct 2-(3-Hydroxy-2-oxoindolin-3-yl)acrylonitrile (ISACN) Modulates Inflammatory Process In vitro and In vivo.

Morita-Baylis-Hillman adducts (MBHA) are synthetic molecules with several biological actions already described in the literature. It has been previously described that adduct 2-(3-hydroxy-2-oxoindolin-3-yl)acrylonitrile (ISACN) has anticancer potential in leukemic cells. Inflammation is often associated with the development and progression of cancer.

Synthesis of 16 New Hybrids from Tetrahydropyrans Derivatives and Morita-Baylis-Hillman Adducts: In Vitro Screening against Leishmania donovani.

Leishmaniases are a group of neglected tropical diseases (NTDs) caused by protozoan parasites from >20 Leishmania species. Visceral leishmaniasis (VL), also known as kala-aza, is the most severe form of leishmaniasis, usually fatal in the absence of treatment in 95% of cases. The Morita-Baylis-Hillman adducts (MBHAs) are being explored as drug candidates against several diseases, one of them being leishmaniasis.

Synthesis and In Vitro Anti Leishmania amazonensis Biological Screening of Morita-Baylis-Hillman Adducts Prepared from Eugenol, Thymol and Carvacrol.

Leishmaniasis represents a series of severe neglected tropical diseases caused by protozoa of the genus and is widely distributed around the world. Here, we present the syntheses of Morita-Baylis-Hillman adducts (MBHAs) prepared from eugenol, thymol and carvacrol, and their bioevaluation against promastigotes of . The new MBHAs are prepared in two steps from essential oils in moderate to good yields and present IC values in the range of 22.
