p-Cymene catabolic pathway in Pseudomonas putida F1: cloning and characterization of DNA encoding conversion of p-cymene to p-cumate [PDF]

Journal of Bacteriology, 1997
Pseudomonas putida F1 utilizes p-cymene (p-isopropyltoluene) by an 11-step pathway through p-cumate (p-isopropylbenzoate) to isobutyrate, pyruvate, and acetyl coenzyme A. The cym operon, encoding the conversion of p-cymene to p-cumate, is located just upstream of the cmt operon, which encodes the further catabolism of p-cumate and is located, in turn ...

In Vitro Antidiabetic Evaluation and Phytochemical Characterization of Sapindus mukorossi Fruit Pericarp Extract

Applied Research, Volume 5, Issue 4, August 2026.
Sapindus mukorossi fruit pericarp is a promising source of polar polyphenols and amphiphilic saponins, with the 70% ethanol extract showing the richest phytochemical profile and strongest α‐amylase inhibition. Its solvent‐dependent bioactive composition suggests potential application in managing postprandial hyperglycemia by modulating dietary starch ...

Phytochemical Composition, In Vitro Antioxidant, Antibacterial, and Antibiofilm Activities of Thymus vulgaris Essential Oil From Tiaret, Algeria

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Thymus vulgaris essential oil (TvEO), largely composed of thymol, showed strong bactericidal activity with Staphylococcus aureus (S. aureus) being most sensitive. TvEO markedly inhibited MRSA biofilm formation and significantly reduced established biofilms. Molecular docking suggests several TvEO components interact with proteins involved in S.

Two New Diterpene Phenols from

Natural Product Communications, 2010
Two new p -cymene based diphenols ( 1-2 ) were isolated from the heartwood of Calocedrus decurrans. Structures were elucidated by 1D and 2D NMR techniques and HRMS. Libocedroquinone ( 3 ) was also isolated as a natural product for the first time.

Lippia umbellata Cav.: Chemical Composition, Insecticidal, and Antimicrobial Activities

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Hexane extracts of Lippia umbellata leaves and flowers contain lupenone, α‐amyrin, and hentriacontane. They exhibit insecticidal activity against Drosophila melanogaster and inhibit AChE in vitro and in silico. Furthermore, the extracts can inhibit the growth of medically important bacteria and yeasts, including multidrug‐resistant strains.

Unlocking Stereodefined Olefins by Z‐Selective Transition Metals‐catalyzed C−H Activations

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
The synthesis of Z‐olefins is an important challenge in synthetic organic chemistry. Within this review, we report a comprehensive overview of transition metals‐catalyzed Z‐selective C–H activations of (hetero)arenes for the synthesis of stereodefined olefins.

Tailored RuNi heterobimetallic complexes as dual catalysts for ROMP of norbornene and ethylene oligomerization

Results in Chemistry
A series of four novel RuL-NiL heterobimetallic complexes was synthesized via the in-situ condensation of primary amine Ru precursors with salicylaldehyde or 3-tert-butylsalicylaldehyde, generating an N,O-chelated iminic bridge that links the two metal ...

Catalytic Deuteration of Amines in Water (D2O) With Ir, Ru, and Rh Pentamethylcyclopentadienyl Dioxime Complexes

ChemistryEurope, Volume 4, Issue 8, August 2026.
A new family of pentamethylcyclopentadienyl (C5Me5, Cp*) iridium(III), rhodium(III), and ruthenium(III) complexes bearing bidentate 1,2‐dioxime ligands was developed and their catalytic performances were evaluated in the hydrogen‐borrowing‐type H/D exchange of amines using D2O as both solvent and deuterium source. Iridium derivatives achieved excellent
