Natural products with γ-pyrone scaffold from Streptomyces.
Review in Applied microbiology and biotechnology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Streptomyces sp. is considered the vast reservoir of bioactive natural products belonging to different classes like polyketides, terpenoids, lanthipeptides, and non-ribosomal peptides to name a few. The ubiquitous distribution of the genus makes them capable of producing distinct compounds. Many of those compounds contain a unique γ-pyrone with various chemical structures and exhibit different bioactivities. One such class, nitrophenyl-γ-pyrone, constitutes different bioactive compounds isolated from Streptomyces sp. from different sources ranging from soil to marine environments. In addition, such compounds have antinematodal, cytotoxicity activities, and inhibition of adipogenesis. These compounds include aureothin (3), spectinabilin (7), and their derivatives. Moreover, there are other compounds like actinopyrones (11-16), benwamycins (22-23), and peucemycin and its derivatives (24-26) that also have antibacterial and anticancer activities. The other group classified as anthra-γ-pyrone has various bioactive natural products. For instance, tetrahydroanthra-γ-pyrone, shellmycin A-D (27-30) possess antibacterial as well as anticancer activities. In addition, the pluramycin family compounds belonging to anthra-γ-pyrone group also possess cytotoxic activity, for instance, kidamycin (31), rubiflavin, and their derivatives (33-37). Xanthones are another important group of natural products that also contain γ-pyrone ring producing different bioactivities. Albofungin (42) and its derivatives (43-46) belong to subgroup polycyclic tetrahydro xanthones that possess antibacterial, anticancer, and antibiofilm, antimacrofouling activities. Similarly, other compounds, belonging to this subgroup, exhibit different bioactivities like antifungal, antimalarial, and antibacterial activities and block transient receptor potential vanilloid 1 (TRPV1). These compounds include cervinomycins (48-55), citreamycins (56-57), sattahipmycin (59), and chrexanthomycins (60-63). This review gives succinct information on the γ-pyrone containing natural products isolated from Streptomyces sp. focusing on their structure and bioactivities. KEY POINTS: • The Streptomyces sp. is the producer of various bioactive natural products including the one with γ-pyrone ring. • These γ-pyrone compounds are structurally different and possess different bioactivities. • The Streptomyces has the potential to produce such compounds and the reservoir of these compounds is expected to increase in the future.
