Polyene Macrolactams from Marine and Terrestrial Sources: Structure, Production Strategies, Biosynthesis and Bioactivities. Mar Drugs 2022; 20:md20060360. [PMID: 35736163 PMCID: PMC9230918 DOI: 10.3390/md20060360] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 05/24/2022] [Accepted: 05/25/2022] [Indexed: 02/04/2023] Open
Abstract
Over the past few decades (covering 1972 to 2022), astounding progress has been made in the elucidation of structures, bioactivities and biosynthesis of polyene macrolactams (PMLs), but they have only been partially summarized. PMLs possess a wide range of biological activities, particularly distinctive fungal inhibitory abilities, which render them a promising drug candidate. Moreover, the unique biosynthetic pathways including β-amino acid initiation and pericyclic reactions were presented in PMLs, leading to more attention from inside and outside the natural products community. According to current summation, in this review, the chem- and bio-diversity of PMLs from marine and terrestrial sources are considerably rich. A systematic, critical and comprehensive overview is in great need. This review described the PMLs’ general structural features, production strategies, biosynthetic pathways and the mechanisms of bioactivities. The challenges and opportunities for the research of PMLs are also discussed.

Cambra JM, Martinez EA, Rodriguez-Martinez H, Gil MA, Cuello C. Transcriptional Profiling of Porcine Blastocysts Produced In Vitro in a Chemically Defined Culture Medium. Animals (Basel) 2021; 11:ani11051414. [PMID: 34069238 PMCID: PMC8156047 DOI: 10.3390/ani11051414] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 05/07/2021] [Accepted: 05/12/2021] [Indexed: 12/21/2022] Open
Abstract
The development of chemically defined media is a growing trend in in vitro embryo production (IVP). Recently, traditional undefined culture medium with bovine serum albumin (BSA) has been successfully replaced by a chemically defined medium using substances with embryotrophic properties such as platelet factor 4 (PF4). Although the use of this medium sustains IVP, the impact of defined media on the embryonic transcriptome has not been fully elucidated. This study analyzed the transcriptome of porcine IVP blastocysts, cultured in defined (PF4 group) and undefined media (BSA group) by microarrays. In vivo-derived blastocysts (IVV group) were used as a standard of maximum embryo quality. The results showed no differentially expressed genes (DEG) between the PF4 and BSA groups. However, a total of 2780 and 2577 DEGs were detected when comparing the PF4 or the BSA group with the IVV group, respectively. Most of these genes were common in both in vitro groups (2132) and present in some enriched pathways, such as cell cycle, lysosome and/or metabolic pathways. These results show that IVP conditions strongly affect embryo transcriptome and that the defined culture medium with PF4 is a guaranteed replacement for traditional culture with BSA.

Abstract
Increased levels of reactive oxygen species (ROS) have been associated with numerous pathophysiological conditions including cancer and inflammation and the ROS stimulus constitutes a potential trigger for drug delivery strategies. Over the past decade, a number of ROS-sensitive functionalities have been identified with the purpose of introducing disease-targeting properties into small molecule drugs - a prodrug strategy that offers a promising approach for increasing the selectivity and efficacy of treatments. This review will provide an overview of the ROS-responsive prodrugs developed to date. A discussion on the current progress and limitations is provided along with a reflection on the unanswered questions that need to be addressed in order to advance this novel approach to the clinic.

Abstract
Leinamycin (LNM) is a potent antitumor antibiotic produced by Streptomyces atroolivaceus S-140. Both in vivo and in vitro characterization of the LNM biosynthetic machinery have established the formation of the 18-membered macrolactam backbone and the C-3 alkyl branch; the nascent product, LNM E1, of the hybrid nonribosomal peptide synthetase (NRPS)-acyltransferase (AT)-less type I polyketide synthase (PKS); and the generation of the thiol moiety at C-3 of LNM E1. However, the tailoring steps converting LNM E1 to LNM are still unknown. Based on gene inactivation and chemical investigation of three mutant strains, we investigated the tailoring steps catalyzed by two cytochromes P450 (P450s), LnmA and LnmZ, in LNM biosynthesis. Our studies revealed that (i) LnmA and LnmZ regio- and stereoselectively hydroxylate the C-8 and C-4' positions, respectively, on the scaffold of LNM; (ii) both LnmA and LnmZ exhibit substrate promiscuity, resulting in multiple LNM analogs from several shunt pathways; and (iii) the C-8 and C-4' hydroxyl groups play important roles in the cytotoxicity of LNM analogs against different cancer cell lines, shedding light on the structure-activity relationships of the LNM scaffold and the LNM-type natural products in general. These studies set the stage for future biosynthetic pathway engineering and combinatorial biosynthesis of the LNM family of natural products for structure diversity and drug discovery.
