Bacterial diversity and chemical ecology of natural product-producing bacteria from Great Salt Lake sediment.

Great Salt Lake (GSL), located northwest of Salt Lake City, UT, is the largest terminal lake in the USA. While the average salinity of seawater is ~3.3%, the salinity in GSL ranges between 5% and 28%.

Topical delivery of seriniquinone for treatment of skin cancer and fungal infections is enabled by a liquid crystalline lamellar phase.

Seriniquinone (SQ) was initially described by our group as an antimelanoma drug candidate and now also as an antifungal drug candidate. Despite its promising in vitro effects, SQ translation has been hindered by poor water-solubility. In this paper, we described the challenging nanoformulation process of SQ, which culminated in the selection of a phosphatidylcholine-based lamellar phase (PLP1).

High-Throughput Screen of Microbial Metabolites Identifies FF ATP Synthase Inhibitors as New Leads for Infection.

Primary amebic meningoencephalitis (PAM), a brain infection caused by a free-living ameba , leads to an extensive inflammation of the brain and death within 1-18 (median 5) days after symptoms begin. Although natural products have played a significant role in the development of drugs for over a century, research focusing on identifying new natural product-based anti- agents is limited. We undertook a large-scale ATP bioluminescence-based screen of about 10,000 unique marine microbial metabolite mixtures against the trophozoites of .

Actinoquinazolinone, a New Quinazolinone Derivative from a Marine Bacterium sp. CNQ-617, Suppresses the Motility of Gastric Cancer Cells.

A HPLC-UV guided fractionation of the culture broth of sp. CNQ-617 has led to the isolation of a new quinazolinone derivative, actinoquinazolinone (), as well as two known compounds, 7-hydroxy-6-methoxy-3,4-dihydroquinazolin-4-one () and 7-methoxy-8-hydroxy cycloanthranilylproline (). The interpretation of 1D, 2D NMR, and MS spectroscopic data revealed the planar structure of .
