Regioselective alkylation of a versatile indazole: Electrophile scope and mechanistic insights from density functional theory calculations

Beilstein Journal of Organic Chemistry
Herein, we report a pair of regioselective N1- and N2-alkylations of a versatile indazole, methyl 5-bromo-1H-indazole-3-carboxylate (6) and the use of density functional theory (DFT) to evaluate their mechanisms. Over thirty N1- and N2-alkylated products

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

Medicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.

Ethyl 3-[6-(4-methoxybenzenesulfonamido)-2H-indazol-2-yl]propanoate monohydrate

Acta Crystallographica Section E, 2013
In the title compound, C19H21N3O5S·H2O, the central indazole system is essentially planar (r.m.s. deviation = 0.012 Å), while both the benzene ring and the mean plane defined by the non-H atoms of the ethyl propionic ester unit (r.m.s ...

Toxicokinetic modelling of the synthetic cannabinoid 5F‐MDMB‐P7AICA and its main metabolite in pigs following pulmonary administration

British Journal of Clinical Pharmacology, EarlyView.
Aims Since their emergence on the drug market, synthetic cannabinoids (SC) are still gaining increasing importance in forensic toxicology. The representatives of the so‐called new psychoactive substances have in common that they have not undergone preclinical safety studies. Hence, knowledge on toxicokinetic (TK) data is sparse.

New indazole-indolizine-triazine hybrid molecules with farnesyltransferase inhibitory activity

Results in Chemistry
A new series of indazole-indolizine-triazine hybrid molecules was obtained by [3 + 2] cycloaddition reaction between newly synthesized nitrogen ylides with indazole skeleton and previously reported dipolarophile 2‐ethynyl‐4,6‐dimethoxy‐1,3,5‐triazine and

Structure‐Based Design, Synthesis, and Biological Evaluation of Oxadiazole–Morpholine Hybrids as Potent PARP‐1 Inhibitors Inducing Apoptosis in Breast Cancer Cells

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT Poly(ADP‐ribose) polymerase‐1 (PARP‐1) plays a central role in the repair of DNA single‐strand breaks and represents an established therapeutic target in cancer treatment. In this study, a series of novel oxadiazole–morpholine hybrid compounds was designed and synthesized using a structure‐based drug design approach to target the catalytic ...

5‐HT2A receptor agonism by tert‐leucinamide and valinamide synthetic cannabinoids: In vitro and in vivo evidence

British Journal of Pharmacology, Volume 183, Issue 16, Page 4715-4734, August 2026.
Abstract Background and Purpose New synthetic cannabinoid receptor agonists (SCRAs) are associated with severe adverse effects, including unexpected psychiatric symptoms. These compounds are mainly active through their potent agonism on the cannabinoid receptors CB1 and CB2.

Ethyl 2-(6-nitro-1H-indazol-1-yl)acetate

IUCrData, 2017
The asymmetric unit of the title compound, C11H11N3O4, comprises two independent molecules, both of which display positional disorder of their ethyl chains in 0.868 (4):0.132 (4) and 0.839 (4):0.161 (4) ratios. The packing is directed by a combination of

Auf dem Weg zu chromoselektiven Transformationen in biologischen Systemen: Perspektiven und Herausforderungen

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.
