Synthesis, Cytotoxic Activity and 2D-QSAR Study of Some Imidazoquinazoline Derivatives
Molecules, 2014 A novel series of 4-substituted amino-7,8-dimethoxy-1-phenylimidazo[1,5-a]quinazolin-5(4H)-one derivatives was designed, synthesized and tested for their antitumor activity against a human mammary carcinoma cell line (MCF7).

Opportunities When Chemistry Meets Biology in Catalysis and Synthesis
Transformative Chemistry, Volume 1, Issue 1, December 2025.Biosynthesis and chemical synthesis possess complementary strengths and limitations. Integrating these two systems across multiple levels offers opportunities for molecular synthesis to become highly efficient, precise, versatile, and scalable in the future, while also ensuring environmental compatibility and resource renewability.

Is co‐existence and/or containment of genetically modified plants possible, and is it important?
New Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1329-1380, December 2025.ABSTRACT Co‐existence and containment of genetically modified (GM) plants has been a contentious issue since GM technologies were first commercially released in the mid‐1990s. In the first decade of commercial GM plant use, there were a significant number of contamination incidents resulting from GM presence in non‐GM crops and seed, some with a ...

Interaction between saflufenacil and imazapyr+imazapic in the management of barnyardgrass and weedy rice and selectivity for irrigated rice [PDF]
Ciência Rural: The use of imidazolinone-tolerant rice cultivars allows selective control of weedy rice and barnyardgrass. However, in many situations, there is a need to add herbicides from other chemical groups to increase the spectrum of weed control. In this sense,

Assessment of genetically modified oilseed rape LBFLFK (application EFSA‐GMO‐DE‐2019‐157)
EFSA Journal, Volume 23, Issue 11, November 2025.Abstract Application EFSA‐GMO‐DE‐2019‐157 (oilseed rape LBFLFK) was submitted to EFSA to be risk assessed as full‐scope, i.e. for import, processing, and food and feed uses, within the EU. Oilseed rape LBFLFK was developed to alter its fatty acid profile and to confer tolerance to imidazolinone herbicides.

Pest Management Science, Volume 81, Issue 10, Page 6807-6819, October 2025.In this study, multiple herbicide resistant mechanisms have been confirmed in two Amaranthus palmeri populations from Spain that survived glyphosate‐ and ALS‐inhibitor herbicides. Our data suggest that the eccDNA and the mutations identified in the ALS gene are the result of an evolutionary event that occurred outside Spain.

Plant Pathology, Volume 74, Issue 8, Page 2377-2391, October 2025.Low frequencies of AvrLm1, 3, 4 and 6 in Leptosphaeria maculans populations show that the corresponding, frequently deployed, Rlm genes have been overcome; the recently deployed Rlm7 (resistance to AvrLm7) is still effective. ABSTRACT Blackleg, caused by the fungal pathogen Leptosphaeria maculans, is a serious constraint to canola production in the ...
