Hammett Correlations in the \u3csup\u3e1\u3c/sup\u3eH NMR Spectra of Some N-Arlydihalonicotinamides [PDF]

open access: yes, 1992
Excellent linear correlations of amide proton chemical shifts (Snh) (in DMSO-d6 ) with Hammett substituent constants (5) for a series of 4-substituted anilides of four dihalonicotinic acid systems were observed. Dihalonicotinanilides with chlorine in the

The Amide Group as Modulator of Crystalline and Liquid Crystalline Structures in Isocyano-alkylanilide Silver (I) Complexes [PDF]

open access: yes, 2015
Producción CientíficaSilver(I) complexes [AgX(CNR] and [Ag(CNR)2]X (X = anionic ligand), containing an amide-functionalized isocyanide, CNR = CN-C6H4-NHCOR, have been synthesized and their X-ray structures have been determined for [Ag(X)(CN-C6H4-NHCOCH3)]

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

open access: yesOikos, EarlyView.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

Comparative Molecular Field Analysis (CoMFA) for Thiotetrazole Alkynylacetanilides, a Non-Nucleoside Inhibitor of HIV-1 Double Mutant K103N/Y181C Reverse Transcriptase

open access: yesE-Journal of Chemistry, 2009
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are allosteric inhibitors of the HIV-1 reverse transcriptase. HIV-1 resistance to nucleoside RT inhibitors such as AZT can arise through mutations in the coding region of RT.

Determination of Hammett Pyridine 3-Aza and 4-Aza Replacement Constants by 1H NMR Studies of Amide Systems [PDF]

open access: yes, 1993
Values for Hammett pyridine 3-aza and 4-aza replacement constants were obtained by correlation of the amide proton chemical shifts (in DMSO) of some N-(3-pyridyl)-and N-(4-pyridyl)-dichloronicotinamides, benzamides and acetamides with those of their N ...

Plant accession and insect infestation, rather than silicon supplementation, shape defence strategies of Arabidopsis halleri towards a leaf beetle

open access: yesPlant Biology, Volume 28, Issue 2, Page 407-419, March 2026.
Chemical and mechanical defences of a metal‐hyperaccumulating plant species Arabidopsis halleri were more influenced by plant accession (genetic background) and insect herbivory by a leaf beetle Phaedon cochleariae than by supplementation of the metalloid silicon.

Characterization of Chickpea Seed Oil and Its Structuring Into Oleogels Using Rice Bran Wax: A Study on the Physicochemical, Thermal, Textural, and Antioxidant Properties for Potential Use in Health‐Conscious and Sustainable Food Products

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Higher rice bran wax ratios produced firmer, more stable oleogels. Lower wax concentrations resulted in weak structuring and phase separation. Oil‐binding capacity increased noticeably with RBW content. Thermal and textural properties improved in proportion to wax concentration.
