Metal?organic frameworks (MOFs), as a new class of porous solid materials, have emerged and their study has established itself very quickly into a productive research field. This short review recaps the recent advancement of chiral MOFs. Here, we present simple, well-ordered instances to classify the mode of synthesis of chiral MOFs, and later demonstrate the potential applications of chiral MOFs in heterogeneous asymmetric catalysis and enantioselective separation. The asymmetric catalysis sections are subdivided based on the types of reactions that have been successfully carried out recently by chiral MOFs. In the part on enantioselective separation, we present the potentiality of chiral MOFs as a stationary phase for high-performance liquid chromatography (HPLC) and high-resolution gas chromatography (GC) by considering fruitful examples from current research work. We anticipate that this review will provide interest to researchers to design new homochiral MOFs with even greater complexity and effort to execute their potential functions in several fields, such as asymmetric catalysis, enantiomer separation, and chiral recognition.

The synthesis of the alkaloid (?)-monophyllidin is described. The molecule is a hybrid of xanthoxyline and (S)-proline, accessible in one-step through a Mannich reaction. In the solid-state, defined structural arrangements with different physical properties are formed. Single crystal X-ray diffraction revealed structures of six distinct polymorphs. In the crystalline state, the alkaloid can host small polar molecules (preferably water), while the (S)-proline moiety is present in the zwitterionic state. Combined with the chelate, which is already present in the xanthoxyline substructure, an ideal disposition for multiple hydrogen bond networks evolve. Therefore, highly water-soluble polymorphs of monophyllidin can form. This structural flexibility explains the many faces of the molecule in terms of structure as well as analytical data. Furthermore, speculations about the biological role of the molecule, with regard to the manifold interactions with water, are presented.

Homochiral metal-organic frameworks (HMOFs) are attractive materials for asymmetric catalysis because they possess high surface area and uniform active sites. A variety of catalytic applications reported so far indicate that HMOFs catalyse a range of transformations, including cyanosilylation, aldol condensation and hydrogenation reactions. Besides contribution to fundamental knowledge, it is also important to evaluate the relevance of organic transformations catalysed by HMOFs and how existing achievements compare with already established enantioselective catalysts. This mini-review gives an overview of the structural design and the catalytic performance of HMOFs and it focuses on the relevance of the chemical reactions tested. It aims at combining the existing demand for heterogeneous asymmetric catalysts with the current knowledge on HMOFs. This is important for the MOF community since it highlights relevant broad scope asymmetric catalytic transformations performed in industry and the insight gained from the catalytic reactions carried out using HMOFs as catalysts. We hope that this work will motivate researchers to rationally design HMOFs with a goal to unveil reaction mechanisms and the interactions between the HMOFs and the reaction molecules for industrially relevant catalytic reactions.

Two cyclotetrapeptides, henceforth named Provipeptides A (1) and B (2), along with five known diketopiperazines (3?7) were isolated from the liquid culture of marine Streptomyces sp. 161a recovered from a sample of sea grass Bryopsis sp. The structures of cyclotetrapeptides and diketopiperazines (DKPs) were established by 1D and 2D NMR data, MS, and by comparison with literature data. The absolute stereochemistry of compounds cyclo-(l-Pro-l-Leu-d-Pro-l-Phe) 1 and cyclo-(-Pro-Ile-Pro-Phe) 2 was established by the Marfey?s method. Compound 1 showed antibacterial activity against rice phytopathogenic strains Burkholderia glumae (MIC = 1.1 mM) and Burkholderia gladioli (MIC = 0.068 mM), compound 2 was active only against B. glumae (MIC = 1.1 mM), and DKP cyclo-[l-Pro-l-Leu] 5 showed to be active against B. gladioli (MIC = 0.3 mM) and B. glumae (MIC = 2.4 mM). Compounds 1 and 2 showed 65% and 50% inhibition of Colletotrichum gloeosporioides (yam pathogen) conidia germination, respectively at a concentration of 1.1 mM.

Biomolecular assembly is a key driving force in nearly all life processes, providing structure, information storage, and communication within cells and at the whole organism level. These assembly processes rely on precise interactions between functional groups on nucleic acids, proteins, carbohydrates, and small molecules, and can be fine-tuned to span a range of time, length, and complexity scales. Recognizing the power of these motifs, researchers have sought to emulate and engineer biomolecular assemblies in the laboratory, with goals ranging from modulating cellular function to the creation of new polymeric materials. In most cases, engineering efforts are inspired or informed by understanding the structure and properties of naturally occurring assemblies, which has in turn fueled the development of predictive models that enable computational design of novel assemblies. This Review will focus on selected examples of protein assemblies, highlighting the story arc from initial discovery of an assembly, through initial engineering attempts, toward the ultimate goal of predictive design. The aim of this Review is to highlight areas where significant progress has been made, as well as to outline remaining challenges, as solving these challenges will be the key that unlocks the full power of biomolecules for advances in technology and medicine.

The gut microbiome, the collection of 100 trillion microorganisms that resides in the intestinal lumen, plays major roles in modulating host physiology. One well-established function of the gut microbiota is that of colonization resistance or the ability of the microbial collective to protect the host against enteric pathogens. Although evidence suggests that these microbes may outcompete some pathogens, there remains a lack of mechanistic understanding that underlies this competitive exclusion. In recent years, there has been great interest in small-molecule metabolites that are produced by the gut microbiota and in understanding how these molecules regulate host-pathogen interactions. In this review, we briefly summarize these findings by focusing on several classes of metabolites that mediate this important process. Understanding these host-microbe interactions in the gut may lead to identification of potential candidates for the development of prophylactics and therapeutics for many infectious diseases that are impacted by the gut microbiome.

Recently, ll-diaminopimelate aminotransferase (ll-DAP-AT), a pyridoxal-5?-phosphate (PLP)-dependent enzyme, was reported to catalyze a key step in the biosynthesis of l-lysine in plants and Chlamydia. Previous screening of a 29201-compound library against ll-DAP-AT identified an o-sulfonamidoarylhydrazide as a reversible inhibitor with IC50 ? 5 muM. Structure-activity relationship (SAR) studies based on this lead compound identified key structural features essential for enzyme inhibition and led to slightly improved inhibitors. Preliminary studies on the mode of inhibition of ll-DAP-AT by this class of compounds are also reported.

Introduction. Chinese medicine syndrome diagnosis is the key requisite in the treatment of male infertility with traditional Chinese medicine (TCM). Kidney-Yang deficiency syndrome (KYDS) is the critical Chinese medicine syndrome of male infertility. To explore the modernized mechanisms of KYDS in male infertility, this study aims to investigate the metabolomics of males with KYDS. Methods. The gas chromatography-mass spectrometry method was applied to analyze the plasma samples of 67 infertile males with KYDS compared with 55 age-matched healthy controls. The chemometric methods including principal component and partial least squares-discriminate analyses were employed to identify the potential biochemical patterns. With the help of the variable importance for the projection and receiver operating characteristic curve analyses, the potential biomarkers were extracted to define the clinical utility. Simultaneously the high-quality KEGG metabolic pathways database was used to identify the related metabolic pathways. Results. The metabolomics profiles of infertile males with KYDS including 10 potential biomarkers and six metabolic pathways were identified. They precisely distinguished infertile males with KYDS from healthy controls. Conclusions. These potential biomarkers and pathways suggest the substantial basis of infertile males with KYDS. The metabolomics profiles highlight the modernized mechanisms of infertile males with KYDS.
