Abstract
Recently, photothermal therapy (PTT) has been recognized as a viable alternative strategy against bacterial biofilm infection. However, the hyperthermia required for PTT to ablate a biofilm usually induces damage in normal tissues/organs nearby. Herein, we developed zeolite-based imidazole framework (ZIF-8)-coated mesoporous polydopamine (MPDA) core-shell nanoparticles and then loaded Pifithrin-μ (PES), a natural inhibitor of heat-shock protein (HSP) that plays an essential role in bacteria resisting heating-induced damage. The ZIF-8 shell of the MPDA@ZIF-8/PES nanoplatform enabled a rapid degradation in response to the acidic environment in bacterial biofilm infection, which triggered the controlled release of PES and Zn ions. As a result, HSP was remarkably suppressed for enhancing PTT efficacy upon mild near-infrared light irradiation. In addition, the release of Zn2+ also had an antibacterial/antibiofilm effect. Thus, the fabricated nanosystem was able to induce the effective elimination of the bacterial biofilm, realizing low-temperature PTT (∼45 °C) with excellent antibacterial efficacy. This work presented here not only provides a facile approach to fabricate the MPDA@ZIF-8/PES nanosystem with the responsiveness of the bacterial infection environment, but also proposes a promising low-temperature PTT strategy to treat bacterial biofilm-infection effectively.

[PMID: 34684777 PMCID: PMC8540241 DOI: 10.3390/molecules26206196] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 10/05/2021] [Accepted: 10/09/2021] [Indexed: 12/26/2022] Open
Abstract
Zeolites and zeolitic imidazolate frameworks (ZIFs) are widely studied as drug carrying nanoplatforms to enhance the specificity and efficacy of traditional anticancer drugs. At present, there is no other systematic review that assesses the potency of zeolites/ZIFs as anticancer drug carriers. Due to the porous nature and inherent pH-sensitive properties of zeolites/ZIFs, the compounds can entrap and selectively release anticancer drugs into the acidic tumor microenvironment. Therefore, it is valuable to provide a comprehensive overview of available evidence on the topic to identify the benefits of the compound as well as potential gaps in knowledge. The purpose of this study was to evaluate the potential therapeutic applications of zeolites/ZIFs as drug delivery systems delivering doxorubicin (DOX), 5-fluorouracil (5-FU), curcumin, cisplatin, and miR-34a. Following PRISMA guidelines, an exhaustive search of PubMed, Scopus, Embase, and Web of Science was conducted. No language or time limitations were used up to 25th August 2021. Only full text articles were selected that pertained to the usage of zeolites/ZIFs in delivering anticancer drugs. Initially, 1279 studies were identified, of which 572 duplicate records were excluded. After screening for the title, abstract, and full texts, 53 articles remained and were included in the qualitative synthesis. An Inter-Rater Reliability (IRR) test, which included a percent user agreement and reliability percent, was conducted for the 53 articles. The included studies suggest that anticancer drug-incorporated zeolites/ZIFs can be used as alternative treatment options to enhance the efficacy of cancer treatment by mitigating the drawbacks of drugs under conventional treatment.

Abstract
Stimulus-responsive pesticide or fertilizer systems have been emerged to improve the use efficiency of agrochemicals, reduce over-application and ensuing environmental problems. However, environmental-friendly synthesis of these systems still remain challenging. In this work, an environmental-friendly synthesis strategy has been developed to form a pesticide and fertilizer combination to achieve the integration of plant protection and nutrient supply. This pesticide-fertilizer combination system was fabricated using ammonium zinc phosphate (ZNP) and in-situ synthesized zeolitic imidazolate framework-8 (ZIF-8) as nutrients resources, and dinotefuran (DNF) as a pesticide. DNF was encapsulated in-situ (loading capacity of 12.32 ± 0.46%) during the ZIF-8 crystal synthesis process, rather than loaded by further adsorption, which improved its stability and prevented premature or rapid release. The hydrophobic ZIF-8 provided a pH-responsive slow-release behavior. The cumulative released DNF within seven days at pH 4.0, 7.0 and 10.0 was 66.30%, 40.41%, and 37.44%, respectively. The pesticide-fertilizer combination system showed significant effects on corn seed pre-cultivation, soil cultivation and pest control. This work provides a strategy for the integration of pesticide and fertilizer, which will reduce negative environmental effects caused by their over-applications and have great potential in modern sustainable agriculture.

Abstract
Black phosphorus (BP) nanosheet is easily oxidized by oxygen and water under ambient environment, thus, reliable BP passivation techniques for biomedical applications is urgently needed. A simple and applicable passivation strategy for biomedical applications was established by encapsulating BP nanosheet into zeolitic imidazole framework-8 (ZIF-8). The resulted BP nanosheet in ZIF-8 (BP@ZIF-8) shows not only satisfied chemical stability in both water and phosphate buffered saline (PBS), but also excellent biocompatibility. Notably, BP nanosheet endows the prepared BP@ZIF-8 with prominent photothermal conversion efficiency (31.90%). Besides passivation BP, ZIF-8 provides the BP@ZIF-8 with high drug loading amount (1353.3 mg g-1). Moreover, the loaded drug can be controlled release by pH stimuli. Both in vitro and in vivo researches verified the resulted BP@ZIF-8 an ideal candidate for tumor multimodal treatments.

Abstract
As one of the most promising drug-delivery carriers due to its small size, easy surface modifiability, and hydrophobic interior, cationic poly(amidoamine) (PAMAM) per se, demonstrated by previous reports and the authors' present study, indicate potential anticancer capability, however, which are restricted by autophagy elicitation. Besides, its side-toxicity profile, having also been extensively documented, limits its translation into the clinic. Herein, the authors design a photoresponsive PAMAM-assembled nanoparticle loaded with the autophagy inhibitor (chloroquine, CQ), which exhibits light responsiveness for precisely controlling drug release and superior dark biosafety. Upon light irradiation, the nanoparticle can dissociate into charged small PAMAM for a significant antitumor effect. Meanwhile, the released CQ can inhibit pro-survival autophagy induced by PAMAM to achieve an excellent synergistic anticancer efficacy in vitro and in vivo. The authors' study provided a vision of utilizing PAMAM as self-carried anticancer therapeutics in combination with an autophagy inhibitor and proposing a cancer therapy with high antitumor efficacy and low side effects to normal tissues.

Abstract
The serious threat of drug-resistant bacterial pathogens has arisen through overuse of antibiotics. Photothermal therapy (PTT) has come to prominence as viable alternative strategy for antibacterial therapy. In this work, we report a NIR/pH dual stimuli-responsive antibacterial formulation based on zeolitic imidazolate frameworks-8 (ZIF-8) with strong antibacterial activity that combines photothermal heating with enhanced antibiotic delivery. ZIF-8 with polydopamine (PDA) surface modification was used to encapsulate the antibiotic vancomycin to construct a dual stimuli-responsive antimicrobial formulation (Van@ZIF-8@PDA). This treatment was tested against Gram-positive Mu50 (a vancomycin-intermediate S. aureus reference strain). Results showed that the PDA coating improved ZIF-8 stability and dispersion, while also conferring a high photothermal conversion efficiency. Hyperthermia activated by near-infrared (NIR) light irradiation, in conjunction with pH-dependent nanoparticle degradation to release vancomycin, enabled tight control of drug delivery that functioned synergistically in the elimination of both planktonic bacteria prior to biofilm formation and established biofilms. We found that this combined formulation compromises cell structure while also degrading bacterial DNA. Moreover, further investigation showed that the Van@ZIF-8@PDA nanoparticles exhibit good biocompatibility, with low toxicity toward host organs and tissues, while also reducing the antibiotic concentration needed for effective bacterial control. Finally, we treated Mu50 in a mouse model of skin abscess and found that Van@ZIF-8@PDA was effective and safe in vivo. Cumulatively, this study shows that this NIR/pH dual stimuli-responsive nanoparticle-based formulation offers a promising potential strategy for clinical application against bacterial infection that circumvents antibiotic resistance.
