1H and 13C-NMR Data of the Simplest Plumeran Indole Alkaloids Isolated from Aspidosperma Species
Molecules, 2012 Indole alkaloids are the chemotaxonomic markers of the Aspidosperma genera. Those that have the simplest plumeran skeleton are classified as the precursors of biosynthetic routes and the intermediates for several synthetic reactions.

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.

Bioactive Chemicals of Importance in Endophyte-Infected Grasses [PDF]
, 2009 Janthitrems are believed to be involved in the observed sporadic cases of AR37- infected perennial ryegrass staggers. Investigations into the role of janthitrems in perennial ryegrass staggers are difficult as isolation of the compounds from the ryegrass

Phytotherapy Research, EarlyView.ABSTRACT Chronic kidney disease (CKD) is driven by persistent inflammation and progressive fibrosis, leading to irreversible renal damage. Gramine (GMN), an indole alkaloid, has broad pharmacological benefits. However, its therapeutic potential against renal fibrosis remains unexplored.

Alkaloids Induce Programmed Cell Death in Bloodstream Forms of Trypanosomes (Trypanosoma b. brucei)
Molecules, 2008 The potential induction of a programmed cell death (PCD) in Trypanosoma b. brucei by 55 alkaloids of the quinoline, quinolizidine, isoquinoline, indole, terpene, tropane, steroid, and piperidine type was studied by measuring DNA fragmentation and changes

Oxaziridines: Versatile Reagents in Modern Organic Synthesis
The Chemical Record, EarlyView.Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Indole Synthesis via Allenyl Ester; Enantioselective Total Synthesis of Geissoschizoline
ChemistryEuropeMethyl indole‐2‐acetate is a key structural motif in plant‐derived indole alkaloids. In this study, a mild and efficient protocol is presented for its preparation using readily available aniline derivatives, which are synthesized from malonic esters. The
