Abstract
Platensilin, platensimycin, and platencin are potent inhibitors of β-ketoacyl-acyl carrier protein synthase (FabF) in the bacterial and mammalian fatty acid synthesis system, presenting promising drug leads for both antibacterial and antidiabetic therapies. Herein, a bioinspired skeleton reconstruction approach is reported, which enables the unified synthesis of these three natural FabF inhibitors and their skeletally diverse analogs, all stemming from a common ent-pimarane core. The synthesis features a diastereoselective biocatalytic reduction and an intermolecular Diels-Alder reaction to prepare the common ent-pimarane core. From this intermediate, stereoselective Mn-catalyzed hydrogen atom-transfer hydrogenation and subsequent Cu-catalyzed carbenoid C-H insertion afford platensilin. Furthermore, the intramolecular Diels-Alder reaction succeeded by regioselective ring opening of the newly formed cyclopropane enables the construction of the bicyclo[3.2.1]-octane and bicyclo[2.2.2]-octane ring systems of platensimycin and platencin, respectively. This skeletal reconstruction approach of the ent-pimarane core facilitates the preparation of analogs bearing different polycyclic scaffolds. Among these analogs, the previously unexplored cyclopropyl analog 47 exhibits improved antibacterial activity (MIC80 = 0.0625 μg/mL) against S. aureus compared to platensimycin.

Abstract
Co-amorphous technology is an emerging approach for pharmaceutical engineering of drugs and drug leads with improved physicochemical properties and bioavailability. Platensimycin (PTM) is a promising natural antibiotic lead that acts on bacterial fatty acid synthase and exhibits excellent antibacterial activity. Despite great strides to improve its poor pharmacokinetics by medicinal chemistry and nanotechnology, there are no convenient oral delivery systems developed. Here, a co-amorphous system of PTM and berberine chloride (BCL) was developed for oral delivery of PTM. Co-amorphous PTM-BCL was prepared by rotary vacuum evaporation method, and systematically characterized by powder X-ray diffraction, temperature modulated differential scanning calorimetry, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). Compared with PTM or BCL alone, the equilibrium solubility and dissolution rate of both of them in the co-amorphous systems decreased significantly, showing the characteristics of sustained release. The molecular interactions between PTM and BCL were mediated by strong charged-mediated hydrogen bonds, based on FTIR, XPS, and NMR-based techniques. The co-amorphous PTM-BCL system showed excellent physiochemical stability at room and elevated (40 °C) temperature under dry conditions. The combination of PTM and BCL showed increased killing of a clinical isolated methicillin-resistant Staphylococcus aureus strain in killing checkerboard assays. Finally, co-amorphous PTM-BCL exhibited 2- or 3-fold longer half-life in rats than that of crystalline and amorphous PTM upon oral administration, respectively. Our study suggests a rational approach to realize the full potential of potent antibiotic PTM, which may be conveniently adapted for engineering of other important pharmaceutics.

Abstract
Type II fatty acid synthases are promising drug targets against major bacterial pathogens. Platensimycin (PTM) is a potent inhibitor against β-ketoacyl-[acyl carrier protein] synthase II (FabF) and β-ketoacyl-[acyl carrier protein] synthase I (FabB), while the poor pharmacokinetics has prevented its further development. In this work, thirty-two PTM derivatives were rapidly prepared via Heck, Sonogashira, and one-pot Sonogashira/cycloaddition cascade reactions based on the Gram-scale synthesis of 6-iodo PTM (4). About half of the synthesized compounds were approximately equipotent to PTM against the tested Staphylococcus aureus strains. Among them, the representative compounds 4, A4, and B8 exhibited different plasma protein binding affinity or stability in the human hepatic microsome assay and showed improved in vivo efficacy over PTM in a mouse peritonitis model. In addition, A4 was also effective in an S. aureus-infected skin mouse model. Our study not only significantly expands the known PTM derivatives with improved antibacterial activities in vivo, but showcased that C–C cross-coupling reactions are useful tools to functionalize natural product drug leads.

Abstract
Skin and soft tissue infections require effective and sustained topical administration. Platensimycin (PTM) is a natural drug lead that targets bacterial fatty acid synthases and has a great potential to treat infections caused by methicillin-resistant Staphylococcus aureus (MRSA). To facilitate the use of PTM against local MRSA infections, we prepared polyacrylamide hydrogels containing polyamidoamine (PAMAM)/PTM nanoparticles (NP-gel(PTM)) for the controlled release of PTM. NP-gel(PTM) can continuously inhibit the growth of MRSA and its biofilm formation in simulated drug flow models in vitro. In situ implantation of NP-gel(PTM) could treat MRSA-infected subcutaneous soft tissues without toxicity. For MRSA-infected skin wounds, NP-gel(PTM) not only showed strong anti-MRSA activity but also accelerated more wound healing than the widely used antibiotic mupirocin. Collectively, PTM is expected to be used in this safe and effective NP-gel delivery platform for the treatment of local infections, which might help to alleviate the current antibiotic resistance crisis.

Abstract
Adamantane has been widely used as a "lipophilic bullet" in drug discovery and development, due to its unique diamond-like architecture with benign pharmacological/ pharmaceutical properties. Platensimycin is a natural product isolated from a soil streptomycete, which contains an adamantane-like moiety extensively modified from a diterpenoid precursor. In the current study, platensic alcohol was semisynthesized from platensimycin and used as an adamantane surrogate in anticancer drug lead adaphostin. The resulting hybrid platensic alcohol/adaphostin compounds, eg. 4a and 4b, exhibited similar cytotoxic activity with adaphostin against the tested cancer cell lines. In particular, 4b generates significantly more reactive oxygen species (ROS) and shows stronger synergy with the clinically used histone deacetylase inhibitor vorinostat than adaphostin, probably due to the presence of two hydroquinone groups. Density functional theory calculation supports that there could be certain π-π stacking interaction in 4b in aqueous solution, which might explain that 4b has similar serum stability with adaphostin. Our study not only leads to the identification of 4b as a potent ROS generating agent, but showcases a simple scaffold hopping strategy to harvest lipophilic scaffolds from natural products.

Abstract
The discovery and clinical use of multitarget monotherapeutic antibiotics is regarded as a promising approach to reduce the development of antibiotic resistance. Platencin (PTN), a potent natural antibiotic initially isolated from a soil actinomycete, targets both FabH and FabF, the initiation and elongation condensing enzymes for bacterial fatty acid biosynthesis. However, its further clinical development has been hampered by poor pharmacokinetics. Herein we report the semisynthesis and biological evaluation of platencin derivatives 1-15 with potent antibacterial activity against methicillin-resistant Staphylococcus aureus in vitro. Some of these PTN analogues showed similar yet distinct interactions with FabH and FabF, as shown by molecular docking, differential scanning fluorometry, and isothermal titration calorimetry. Compounds 3, 8, 10, and 14 were further evaluated in a mouse peritonitis model, among which 8 showed in vivo antibacterial activity comparable to that of PTN. Our results suggest that semisynthetic modification of PTN is a rapid route to obtain active PTN derivatives that might be further developed as promising antibiotics against drug-resistant major pathogens.

Abstract
The outer membrane (OM) of Gram-negative bacteria provides an efficient barrier against external noxious compounds such as antimicrobial agents. Associated with drug target modification, it contributes to the overall failure of chemotherapy. In the complex OM architecture, Lipid A plays an essential role by anchoring the lipopolysaccharide in the membrane and ensuring the spatial organization between lipids, proteins, and sugars. Currently, the targets of almost all antibiotics are intracellularly located and require translocation across membranes. We report herein an integrated view of Lipid A synthesis, membrane assembly, a structure comparison at the molecular structure level of numerous Gram-negative bacterial species, as well as its recent use as a target for original antibacterial molecules. This review paves the way for a new vision of a key membrane component that acts during bacterial adaptation to environmental stresses and for the development of new weapons against microbial resistance to usual antibiotics.

Abstract
Bacterial fatty acid synthases are promising antibacterial targets against multidrug-resistant pathogens. Platensimycin (PTM) is a potent FabB/FabF inhibitor, while its poor pharmacokinetics hampers the clinical development. In this study, a focused library of PTM derivatives was prepared through thiolysis of PTM oxirane (1), followed by various C-C cross-coupling reactions in high yields. Antibacterial screening of these compounds in vitro yielded multiple hits with improved anti-Staphylococcus activities over PTM. Among them, compounds A1, A3, A17, and A28 exhibited improved antibacterial activities over PTM against methicillin-resistant Staphylococcus aureus (MRSA) in a mouse peritonitis model. Compound A28 was further shown to be effective against MRSA infection in a mouse wound model, in comparison to mupirocin. Therefore, the facile preparation and screening of these PTM derivatives, together with their potent antibacterial activities in vivo, suggest a promising strategy to improve the antibacterial activity and pharmacokinetic properties of PTM.

Abstract
Staphylococcus aureus is one of the most common pathogens causing hospital-acquired and community-acquired infections. Methicillin-resistant S. aureus (MRSA)-formed biofilms in wounds are difficult to treat with conventional antibiotics. By targeting FabB/FabF of bacterial fatty acid synthases, platensimycin (PTM) was discovered to act as a promising natural antibiotic against MRSA infections. In this study, PTM and its previously synthesized sulfur-Michael derivative PTM-2t could reduce over 95% biofilm formation by S. aureus ATCC 29213 when used at 2 μg/mL in vitro. Topical application of ointments containing PTM or PTM-2t (2 × 4 mg/day/mouse) was successfully used to treat MRSA infections in a BABL/c mouse burn wound model. As a potential prodrug lead, PTM-2t showed improved in vivo efficacy in a mouse peritonitis model compared with PTM. Our study suggests that PTM and its analogue may be used topically or locally to treat bacterial infections. In addition, the use of prodrug strategies might be instrumental to improve the poor pharmacokinetic properties of PTM.

Abstract
Bioinspired sulfa-Michael/aldol cascade reactions have been developed for the semisynthesis of sulfur-containing heterocyclic derivatives of platensimycin and platencin, with three newly formed contiguous stereogenic centers. Density functional theory calculations revealed the mechanism for the stereochemistry control. This method was used in a synthesis of a platensimycin thiophene analogue with potent antibacterial activities against Staphylococcus aureus.
