Abstract
Bacteria produce natural products (NPs) via biosynthetic gene clusters. Unfortunately, many biosynthetic gene clusters are silent under traditional laboratory conditions. To access novel NPs, a better understanding of their regulation is needed. γ-Butyrolactones, including the A-factor and Streptomyces coelicolor butanolides, SCBs, are a major class of Streptomyces' hormones. Study of these hormones has been limited due to challenges in accessing them in stereochemically pure forms. Herein, we describe an efficient route to (R)-paraconyl alcohol, a key intermediate for these molecules, as well as a biocatalytic method to access the exocyclic hydroxyl group that differentiates A-factor-type from SCB-type hormones. Utilizing these methods, a library of hormones have been synthesized and tested in a green fluorescent protein reporter assay for their ability to relieve repression by the repressor ScbR. This allowed the most quantitative structure-activity relationship of γ-butyrolactones and a cognate repressor to date. Bioinformatics analysis strongly suggests that many other repressors of NP biosynthesis likely bind similar molecules. This efficient, diversifiable synthesis will enable further investigation of the regulation of NP biosynthesis.

Abstract
Streptomyces is a model bacterium to study multicellular differentiation and the major reservoir for antibiotics discovery. However, the cellular-level lifecycle of Streptomyces has not been well studied due to its complexity and lack of research tools that can mimic their natural conditions. In this study, we developed a simple microfluidic chip for the cultivation and observation of the entire lifecycle of Streptomyces development from the single-cell perspective. The chip consists of channels for loading samples and supplying nutrients, microwell arrays for the seeding and growth of single spores, and air chambers beside the microwells that facilitate the development of aerial hyphae and spores. A unique feature of this chip is that each microwell is surrounded by a 1.5 µm nanogap connected to an air chamber, which provides a stabilized water-air interface. We used this chip to observe the lifecycle development of Streptomyces coelicolor and Streptomyces griseus germinated from single spores, which revealed differentiation of aerial hyphae with progeny spores at micron-scale water-air interfaces and air chambers. Finally, we demonstrated the applicability of this chip in phenotypic assays by showing that the microbial hormone A-Factor is involved in the regulatory pathways of aerial hyphae and spore formation. The microfluidic chip could become a robust tool for studying multicellular differentiation, single-spore heterogeneity, and secondary metabolism of single-spore germinated Streptomyces.

Abstract
Streptomyces is the largest and most significant genus of Actinobacteria, comprising 961 species. These Gram-positive bacteria produce many versatile and important bioactive compounds; of these, antibiotics, specifically the enhancement or activation of their production, have received extensive research attention. Recently, various biotic and abiotic elicitors have been reported to modify the antibiotic metabolism of Streptomyces, which promotes the production of new antibiotics and bioactive metabolites for improvement in the yields of endogenous products. However, some elicitors that obviously contribute to secondary metabolite production have not yet received sufficient attention. In this study, we have reviewed the functions and mechanisms of chemicals, novel microbial metabolic elicitors, microbial interactions, enzymes, enzyme inhibitors, environmental factors, and novel combination methods regarding antibiotic production in Streptomyces. This review has aimed to identify potentially valuable elicitors for stimulating the production of latent antibiotics or enhancing the synthesis of subsistent antibiotics in Streptomyces. Future applications and challenges in the discovery of new antibiotics and enhancement of existing antibiotic production using elicitors are discussed.

Experimental and Computational Studies Unraveling the Peculiarity of Enolizable Oxoesters in the Organocatalyzed Mannich-Type Addition to Cyclic N-Acyl Iminium Ions. Molecules 2020; 25:molecules25081903.

Abstract
γ− and δ-Oxoesters are easily available starting materials that have been sparingly used in some organocatalyzed reactions proceeding with a high enantioselectivity. In our experimentation we found that the use of these compounds as the enolizable (nucleophilic) component in organocatalyzed Mannich-type reactions using in situ-generated cyclic N-acyl iminium ions gave low diastereoselectivity and low to moderate values of enantioselectivity. This significant drop of facial selectivity with respect to simple aliphatic aldehydes has been rationalized by means of density functional theory (DFT) calculations.

Abstract
The stereoselective sequential spirocyclopropanation/Cloke-Wilson rearrangement reactions have been developed to synthesize γ-butyrolactones using alkylidene Meldrum's acids and benzyl halides. The DBU-promoted spirocyclopropanation was carried out efficiently at room temperature to generate trans-isomeric spirocyclopropyl Meldrum's acid, and the following stereospecific thermal decarboxylative Cloke-Wilson rearrangement afforded trans-γ-butyrolactones. A variety of aromatic and aliphatic Meldrum's acid derived olefins and benzyl halides were tolerated. Various trans-β,γ-disubstituted γ-butyrolactones were produced with moderate to good overall yields from 46 to 96% and excellent diastereoselectivities.

Activation of paulomycin production by exogenous γ-butyrolactone signaling molecules in Streptomyces albidoflavus J1074. Appl Microbiol Biotechnol 2020; 104:1695-1705.

Abstract
The interspecies communication roles of γ-butyrolactones (GBLs) have been described for a long time but are still poorly understood. Herein, we analyzed more than 1000 Streptomyces strains and noticed a big quantitative gap between the strains with GBL biosynthetic genes and the strains with GBL receptor genes, which implies the wide-spread of GBLs as interspecies signals in Streptomyces and their great potential in the activation of silent natural product gene clusters. Streptomyces albidoflavus J1074, which has one GBL receptor gene but no GBL biosynthetic gene, was chosen as a target to study the possible interspecies communication roles of GBLs. At first, the GBL biosynthetic genes from Streptomyces coelicolor M145 were expressed in S. albidoflavus J1074, which enabled the S. albidoflavus strains to synthesize Streptomyces coelicolor butanolides (SCBs) and activated the production of paulomycins. Further studies showed that this activation process requires the participation of the GBL receptor gene XNR_4681. The results suggest that the expression of exogenous GBL biosynthetic genes can modulate the metabolisms of GBL non-producing strains, and this regulation role might be meaningful for silent gene cluster activation in Streptomyces. At final, we synthesized racemic-SCB2 and tried to simplify the activation process by adding SCB2 directly to S. albidoflavus J1074, which unfortunately failed to induce paulomycin production.

Abstract
A simple and efficient approach to enantioenriched α,β-disubstituted γ-butyrolactones has been developed through multifunctional modular organocatalysis in a highly enantioselective (>99% ee) and diastereoselective (>30:1) manner following a one-pot sequential Michael-hemiacetalization-oxidation reaction. The catalytic process has great substrate compatibility, and the products have been transformed to synthetically useful molecules. The methodology has also been applied to the formal synthesis of (+)-Pilocarpine.
