Angewandte Chemie International Edition, Accepted Article.The total synthesis of isodaphlongamine H based on a lactam strategy, which enables quick access to complex cyclic amines, is described. The strategy begins with alkylation of a chiral lactam and subsequent N‐oxidation via an imino ether to afford the N‐hydroxylactam.

Antibacterial effects of natural compounds on biofilm formation of Streptococcus mutans
Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1426-1433, December 2022., 2022 Abstract Streptococcus mutans is the main cariogenic pathogen in the oral cavity, considered to contribute toward oral diseases. S. mutans is predominantly entrapped in plaque biofilms. Objectives In this study, we surveyed the antibacterial activity of natural compounds in terms of the biofilm production of S. mutans. Material and Methods We extracted

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In this work, Calotropis procera latex extract (CPLE) was evaluated as an environmentally benign corrosion inhibition on mild steel in 1‐M HCl using gravimetric, electrochemical, surface, and computational approaches. The results revealed that CPLE exhibited an efficient corrosion inhibitor with the efficiency of 94.26% and 93.10% at 200‐ppm ...

Strictosidine, the common precursor for monoterpenoid indole alkaloids with 3 α and 3 β configuration [PDF]
, 1978 Recently we reported that strictosidine (l> is the key intermediate in the formation of the three classes (ASDidOf3DeIm5, Iboga, Corynanthe) of monoterpenoid indole alkaloids In Catharanthus roseus and a variety of other plant species in cell culture ...

Analysis of plant metabolomics data using identification‐free approaches
Applications in Plant Sciences, EarlyView.Abstract Plant metabolomes are structurally diverse. One of the most popular techniques for sampling this diversity is liquid chromatography–mass spectrometry (LC‐MS), which typically detects thousands of peaks from single organ extracts, many representing true metabolites.

A cytotoxic survey on 2‐amino‐1H‐imidazol based synthetic marine sponge alkaloid analogues
Drug Development Research, Volume 83, Issue 8, Page 1906-1922, December 2022., 2022 Abstract Here, we describe the synthesis and biologic activity evaluation of 20 novel synthetic marine sponge alkaloid analogues with 2‐amino‐1H‐imidazol (2‐AI) core. Cytotoxicity was tested on murine 4T1 breast cancer, A549 human lung cancer, and HL‐60 human myeloid leukemia cells by the resazurin assay.

A new spin on chemotaxonomy: Using non‐proteogenic amino acids as a test case
Applications in Plant Sciences, EarlyView.Abstract Premise Specialized metabolites serve various roles for plants and humans. Unlike core metabolites, specialized metabolites are restricted to certain plant lineages; thus, in addition to their ecological functions, specialized metabolites can serve as diagnostic markers of plant lineages.
