Abstract
Bacterial patterning has emerged as a pivotal biofabrication technique in the biomedical field. In the past 2 decades, a diverse array of bacterial patterning approaches have been developed to enable the precise manipulation of the spatial distribution of bacterial patterns for various applications. Despite the significance of these advancements, there is a deficiency of review articles providing an overview of bacterial patterning technologies. In this mini-review, we systematically summarize the progress of bacterial patterning over the past 2 decades. This review commences with an elucidation of the definition and fundamental principles of bacterial patterning. Subsequently, we introduce the established bacterial patterning strategies, accompanied by discussions about the advantages and limitations of each approach. Furthermore, we showcase the biomedical applications of these strategies, highlighting their efficacy in spatial control of biofilms, biosensing, and biointervention. Finally, this mini-review is concluded with a summary and an outlook on future challenges and opportunities. It is anticipated that this mini-review can serve as a concise guide for those who are interested in this exciting and rapidly evolving research area.

Photochemically controlled activation of STING by CAIX-targeting photocaged agonists to suppress tumor cell growth. Chem Sci 2023; 14:5956-5964. [PMID: 37293644 PMCID: PMC10246697 DOI: 10.1039/d3sc01896b] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 05/05/2023] [Indexed: 06/10/2023] Open
Abstract
Controllable activation of the innate immune adapter protein - stimulator of interferon genes (STING) pathway is a critical challenge for the clinical development of STING agonists due to the potential "on-target off-tumor" toxicity caused by systematic activation of STING. Herein, we designed and synthesized a photo-caged STING agonist 2 with a tumor cell-targeting carbonic anhydrase inhibitor warhead, which could be readily uncaged by blue light to release the active STING agonist leading to remarkable activation of STING signaling. Furthermore, compound 2 was found to preferentially target tumor cells, stimulate the STING signaling in zebrafish embryo upon photo-uncaging and to induce proliferation of macrophages and upregulation of the mRNA expression of STING as well as its downstream NF-kB and cytokines, thus leading to significant suppression of tumor cell growth in a photo-dependent manner with reduced systemic toxicity. This photo-caged agonist not only provides a powerful tool to precisely trigger STING signalling, but also represents a novel controllable STING activation strategy for safer cancer immunotherapy.

Abstract
Mitogen-activated protein kinase kinases 1/2 (MEK1/2) play critical roles in the canonical RAS/RAF/MEK/ERK pathway. Highly selective and potent non-ATP-competitive allosteric MEK1/2 inhibitors have been developed, and three of them were clinically approved for the treatment of BRAFV600 -mutant melanoma. However, the accompanying side effects of the systemically administered MEK1/2 drugs largely constrain their tolerable doses and efficacy. In this study, a series of mirdametinib-based optically activatable MEK1/2 inhibitors (opti-MEKi) were designed and synthesized. A structural-based design led to the discovery of photocaged compounds with dramatically diminished efficacy in vitro, whose activities can be spatiotemporally induced by short durations of irradiation of ultraviolet (365 nm) light. We demonstrated the robust photoactivation of MEK1/2 inhibition and antimelanoma activity in cultured human cells, as well as in a xenograft zebrafish model. Taken together, the modular approach presented herein provides a method for the optical control of MEK1/2 inhibitor activity, and these data support the further development of optically activatable agents for light-mediated antimelanoma phototherapy.

Abstract
![]()
Photolabile protecting
groups (PPGs) enable the precise activation
of molecular function with light in many research areas, such as photopharmacology,
where remote spatiotemporal control over the release of a molecule
is needed. The design and application of PPGs in recent years have
particularly focused on the development of molecules with high molar
absorptivity at long irradiation wavelengths. However, a crucial parameter,
which is pivotal to the efficiency of uncaging and which has until
now proven highly challenging to improve, is the photolysis quantum
yield (QY). Here, we describe a novel and general approach to greatly
increase the photolysis QY of heterolytic PPGs through stabilization
of an intermediate chromophore cation. When applied to coumarin PPGs,
our strategy resulted in systems possessing an up to a 35-fold increase
in QY and a convenient fluorescent readout during their uncaging,
all while requiring the same number of synthetic steps for their preparation
as the usual coumarin systems. We demonstrate that the same QY engineering
strategy applies to different photolysis payloads and even different
classes of PPGs. Furthermore, analysis of the DFT-calculated energy
barriers in the first singlet excited state reveals valuable insights
into the important factors that determine photolysis efficiency. The
strategy reported herein will enable the development of efficient
PPGs tailored for many applications.

Abstract
We exploit two reactive chromophores to establish sequence-independent photochemical activation, employing ortho-methyl benzaldehyde (oMBA) and N,N-(dimethylamino)pyrene aryl tetrazole (APAT) with N-(2-hydroxy)ethyl maleimide (NHEM), without any additives. Critically, the order of the irradiation sequence is irrelevant, as the shorter wavelength does not activate the higher wavelength activated species. Therefore, full sequence-independent λ-orthogonality is achieved through differences in both the reaction quantum yields (Φ r,oMBA and Φ r,APAT) and wavelength-dependent reactivity profiles of the employed chromophores.

Abstract
Despite its promising role in the active control of biological functions by light, photocaging remains untested in acetylcholinesterase (AChE), a key enzyme in the cholinergic family. Here, we describe synthesis, photochemical properties and biochemical activities of two caged oxime compounds applied in the photocontrolled reactivation of the AChE inactivated by reactive organophosphate. Each of these consists of a photocleavable coumarin cage tethered to a known oxime reactivator for AChE that belongs in an either 2-(hydroxyimino)acetamide or pyridiniumaldoxime class. Of these, the first caged compound was able to successfully go through oxime uncaging upon irradiation at long-wavelength ultraviolet light (365 nm) or visible light (420 nm). It was further evaluated in AChE assays in vitro under variable light conditions to define its activity in the photocontrolled reactivation of paraoxon-inactivated AChE. This assay result showed its lack of activity in the dark but its induction of activity under light conditions only. In summary, this article reports a first class of light-activatable modulators for AChE and it offers assay methods and novel insights that help to achieve an effective design of caged compounds in the enzyme control.

Abstract
Synthetic microbial cocultures carry enormous potential for applied biotechnology and are increasingly the subject of fundamental research. So far, most cocultures have been designed and characterized based on bulk cultivations without considering the potentially highly heterogeneous and diverse single-cell behavior. However, an in-depth understanding of cocultures including their interacting single cells is indispensable for the development of novel cultivation approaches and control of cocultures. We present the development, validation, and experimental characterization of an optochemically controllable bacterial coculture on a microcolony level consisting of two Corynebacterium glutamicum strains. Our coculture combines an l-lysine auxotrophic strain together with a l-lysine-producing variant carrying the genetically IPTG-mediated induction of l-lysine production. We implemented two control approaches utilizing IPTG as inducer molecule. First, unmodified IPTG was supplemented to the culture enabling a medium-based control of the production of l-lysine, which serves as the main interacting component. Second, optochemical control was successfully performed by utilizing photocaged IPTG activated by appropriate illumination. Both control strategies were validated studying cellular growth on a microcolony level. The novel microfluidic single-cell cultivation strategies applied in this work can serve as a blueprint to validate cellular control strategies of synthetic mono- and cocultures with single-cell resolution at defined environmental conditions.

Abstract
The photoactivatable chemically induced dimerization (photo-CID) technique for tag-fused proteins is one of the most promising methods for regulating subcellular protein translocations and protein-protein interactions. However, light-induced covalent protein dimerization in living cells has yet to be established, despite its various advantages. Herein, we developed a photoactivatable covalent protein-labeling technology by applying a caged ligand to the BL-tag system, a covalent protein labeling system that uses mutant β-lactamase. We further developed CBHD, a caged protein dimerizer, using caged BL-tag and HaloTag ligands, and achieved light-induced protein translocation from the cytoplasm to subcellular regions. In addition, this covalent photo-CID system enabled quick protein translocation to a laser-illuminated microregion. These results indicate that the covalent photo-CID system will expand the scope of CID applications in the optical manipulation of cellular functions.

Abstract
Abstract
Achieving activatable antibiotics represents one promising solution to tackle the occurrence of side effects, one major issue now plaguing antibiotic usage in collagen-based biomaterials. Despite considerable effort, however, rationale design of activatable antibiotics that display high activation efficiency and uncompromised bactericidal potency in the activated state remains difficult. Here, we demonstrate a design principle that helps to address this challenge. This strategy differs from previous attempts by underscoring photolytic removal of a functionality directly conjugated to the pharmacophore of an antibiotic, enabling not only an activation efficiency significantly improved beyond previous light-activatable antibiotics, but also bactericidal activity in the activated state as potent as the parent drug.

Abstract
Predicting the conversion and selectivity of a photochemical experiment is a conceptually different challenge compared to thermally induced reactivity. Photochemical transformations do not currently have the same level of generalized analytical treatment due to the nature of light interaction with a photoreactive substrate. Herein, we bridge this critical gap by introducing a framework for the quantitative prediction of the time-dependent progress of photoreactions via common LEDs. A wavelength and concentration dependent reaction quantum yield map of a model photoligation, i.e., the reaction of thioether o-methylbenzaldehydes via o-quinodimethanes with N-ethylmaleimide, is initially determined with a tunable laser system. Combined with experimental parameters, the data are employed to predict LED-light induced conversion through a wavelength-resolved numerical simulation. The model is validated with experiments at varied wavelengths. Importantly, a second algorithm allows the assessment of competing photoreactions and enables the facile design of λ-orthogonal ligation systems based on substituted o-methylbenzaldehydes.

Abstract
The spatial and temporal control of bioactivity of small molecules by light (photopharmacology) constitutes a promising approach for study of biological processes and ultimately for the treatment of diseases. In this study, we investigated two different "caged" antibiotic classes that can undergo remote activation with UV-light at λ = 365 nm, via the conjugation of deactivating and photocleavable units through a short synthetic sequence. The two widely used antibiotics vancomycin and cephalosporin were thus enhanced in their performance by rendering them photoresponsive and thereby suppressing undesired off-site activity. The antimicrobial activity against Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 29213, S. aureus ATCC 43300 (MRSA), Escherichia coli ATCC 25922, and Pseudomonas aeruginosa ATCC 27853 could be spatiotemporally controlled with light. Both molecular series displayed a good activity window. The vancomycin derivative displayed excellent values against Gram-positive strains after uncaging, and the next-generation caged cephalosporin derivative achieved good and broad activity against both Gram-positive and Gram-negative strains after photorelease.

Abstract
Photoactivatable (alternatively, photoremovable, photoreleasable, or photocleavable) protecting groups (PPGs), also known as caged or photocaged compounds, are used to enable non-invasive spatiotemporal photochemical control over the release of species of interest. Recent years have seen the development of PPGs activatable by biologically and chemically benign visible and near-infrared (NIR) light. These long-wavelength-absorbing moieties expand the applicability of this powerful method and its accessibility to non-specialist users. This review comprehensively covers organic and transition metal-containing photoactivatable compounds (complexes) that absorb in the visible- and NIR-range to release various leaving groups and gasotransmitters (carbon monoxide, nitric oxide, and hydrogen sulfide). The text also covers visible- and NIR-light-induced photosensitized release using molecular sensitizers, quantum dots, and upconversion and second-harmonic nanoparticles, as well as release via photodynamic (photooxygenation by singlet oxygen) and photothermal effects. Release from photoactivatable polymers, micelles, vesicles, and photoswitches, along with the related emerging field of photopharmacology, is discussed at the end of the review.

Abstract
Despite its importance in the design of photocaged molecules, less attention is focused on linker chemistry than the cage itself. Here, we describe unique uncaging properties displayed by two coumarin-caged thymidine compounds, each conjugated with (2) or without (1) an extended, self-immolative spacer. Photolysis of 1 using long-wavelength UVA (365 nm) or visible (420, 455 nm) light led to the release of free thymidine along with the competitive generation of a thymidine-bearing recombination product. The occurrence of this undesired side reaction, which is previously unreported, was not present with the photolysis of 2, which released thymidine exclusively with higher quantum efficiency. We propose that the spatial separation between the cage and the substrate molecule conferred by the extended linker can play a critical role in circumventing this unproductive reaction. This report reinforces the importance of linker selection in the design of coumarin-caged oligonucleosides and other conjugates.

Abstract
A novel nanoparticle (Au-LTSL-GA.A) uses the thermosensitive liposome (LTSL) to encapsulate ganoderic acid A (GA.A), which successfully transforms the polarity of GA.A and has excellent water solubility. The multifunctional Au-LTSL-GA.A, a self-assembled thermal nanomaterial, was used in antibacterial and anticancer applications in combination with near-infrared (NIR) irradiation. The designed Au-LTSL-GA.A nanoparticle was used as a nano-photosensitizer to achieve synergistic photochemotherapy based on the phototherapy sensitization property of Au nanorods (NRs) and antitumour activity of GA.A. In the antibacterial experiments, the Au-LTSL-GA.A + NIR irradiation had a broad-spectrum antibacterial effect, exhibiting a strong antibacterial activity against drug-resistant Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) compared with the raw GA.A and LTSL-GA.A. In the anticancer experiments, Au-LTSL-GA.A + NIR irradiation, which combined phototherapy sensitization property of Au NRs with antitumour activity of GA.A, exhibited high anticancer activity against MCF-7 cells. The IC50 value of Au-LTSL-GA.A + NIR irradiation (12.1 ± 1.3 μg/mL) was almost similar to cisplatin in MCF-7 cells. The evaluation of the potential in vivo toxicity of Au-LTSL-GA.A revealed no toxicity in mice. The results of this study suggest that Au-LTSL-GA.A has a wide range of potential industrial and clinical applications, such as in antibacterial treatment and cancer photochemotherapy.

Abstract
Layer-by-layer (LbL) self-assembly of polymer coatings is a bottom-up fabrication technique with broad applicability across a wide range of materials and applications that require control over interfacial properties. While most LbL coatings are chemically uniform in directions both tangent and perpendicular to their substrate, control over the properties of surface coatings as a function of space can enhance their function. To contribute to this rapidly advancing field, our group has focused on the top-down spatiotemporal control possible with photochemically reactive LbL coatings, harnessed through charge-shifting polyelectrolytes enabled by photocleavable ester pendants. The photolysis of the photocleavable esters degrades LbL films containing these polyelectrolytes. The chemical structures of the photocleavable groups dictate the wavelengths responsible for disrupting these coatings, ranging from ultraviolet to near-infrared in our work. In addition, spatially segregating reactive groups into "compartments" within LbL films has enabled us to fabricate reactive free-standing polymer films and multiheight photopatterned coatings. Overall, by combining bottom-up and top-down approaches, photoreactive LbL films enable precise control over the interfacial properties of polymer and composite coatings.

Abstract
![]()
Circadian clocks,
biological timekeepers that are present in almost
every cell of our body, are complex systems whose disruption is connected
to various diseases. Controlling cellular clock function with high
temporal resolution in an inducible manner would yield an innovative
approach for the circadian rhythm regulation. In the present study,
we present structure-guided incorporation of photoremovable protecting
groups into a circadian clock modifier, longdaysin, which inhibits
casein kinase I (CKI). Using photodeprotection by UV or visible light
(400 nm) as the external stimulus, we have achieved quantitative and
light-inducible control over the CKI activity accompanied by an accurate
regulation of circadian period in cultured human cells and mouse tissues,
as well as in living zebrafish. This research paves the way for the
application of photodosing in achieving precise temporal control over
the biological timing and opens the door for chronophotopharmacology
to deeper understand the circadian clock system.

Abstract
We report light-induced reactions in a two-chromophore system capable of sequence-independent λ-orthogonal reactivity relying solely on the choice of wavelength and solvent. In a solution of water and acetonitrile, LED irradiation at λmax =285 nm leads to full conversion of 2,5-diphenyltetrazoles with N-ethylmaleimide to the pyrazoline ligation products. Simultaneously present o-methylbenzaldehyde thioethers are retained. Conversely, LED irradiation at λmax =382 nm is used to induce ligation of the o-methylbenzaldehydes in acetonitrile with N-ethylmaleimide via o-quinodimethanes, while 2,5-diphenyltetrazoles also present are retained. This unprecedented photochemical selectivity is achieved through control of the number and wavelength of incident photons as well as favorable optical properties and quantum yields of the reactants in their environment.

Abstract
The current available therapeutics face several challenges such as the development of ideal drug delivery systems towards the goal of personalized treatments for patients benefit. The application of light as an exogenous activation mechanism has shown promising outcomes, owning to the spatiotemporal confinement of the treatment in the vicinity of the diseased tissue, which offers many intriguing possibilities. Engineering therapeutics with light responsive moieties have been explored to enhance the bioavailability, and drug efficacy either in vitro or in vivo. The tailor-made character turns the so-called photocaged compounds highly desirable to reduce the side effects of drugs and, therefore, have received wide research attention. Herein, we seek to highlight the potential of photocaged compounds to obtain a clear understanding of the mechanisms behind its use in therapeutic delivery. A deep overview on the progress achieved in the design, fabrication as well as current and possible future applications in therapeutics of photocaged compounds is provided, so that novel formulations for biomedical field can be designed.

Abstract
Bacterial resistance has caused a global healthcare emergency due to the buildup of antibiotics in the environment. Novel approaches that enable highly efficient bactericide and auto inactivation are highly desired. Past researches mainly focused on the on-off bactericidal ability of antibiotics, which often displays unsatisfactory bactericidal efficiency. Herein, we report a Trojan antibiotic that considers the affinity of antibiotics to bacteria. A disguised host-guest supramolecule based on cucurbituril (CB[7]) and a bola-type azobenzene compound with glycosylamine heads at both ends is synthesized. This supramolecule has a surface fully decorated with sugar-like components, which are highly analogous to wall components of bacteria. This Trojan antibiotic is benign to a wide spectrum of bacteria at a weak basic pH of approximately 9.0 under daylight conditions. However, this antibiotic becomes a potent bactericide toward both Gram-negative and Gram-positive bacteria at pH 4.0 under 365 nm UV irradiation. The dual use of pH and UV light greatly enhances the efficiency of the bactericidal effect so that the 50% minimum inhibitory concentration (MIC50) of the Trojan antibiotic is at least 10 times smaller than that of conventional drugs, and the removal of the UV source and reversal of pH automatically stop the antibacterial behavior, which prevents the buildup of active antimicrobial materials in the environment. We expect that the presented Trojan supramolecular strategy may open up a new paradigm in the fight against bacterial resistance.

Abstract
The use of nanotechnology to improve treatment efficacy and reduce side effects is central to nanomedicine. In this context, stimuli-responsive drug delivery systems (DDS) such as chemical/physical gels or nanoparticles such as polymersomes, micelles or nanogels are particularly promising and are the focus of this review. Several stimuli have been considered but light as an exogenous trigger presents many advantages that are pertinent for clinical applications such as high spatial and temporal control and low cost. Underlying mechanisms required for the release of therapeutic agents in vitro and in vivo range from the molecular scale, namely photoisomerization, hydrophobicity photoswitching, photocleavage or heat generation via nanoheaters, through to the macromolecular scale. As well as these approaches, DDS destabilization, DDS permeation pore unblocking and formation are discussed.

Abstract
The antibiotic penicillin G cannot be completely incorporated into hydrophobic lipid-membranes owing to its hydrophilicity. Through modification with a hydrophobic and photolabile protecting group, penicillin G was effectively incorporated into liposomes and released by photoirradiation at 365 nm. Penicillin G as an antibiotic was released from liposomes by increase of hydrophilicity by photocleavage of a hydrophobic protecting group.![]()

Abstract
![]()
Selectivity
remains a major challenge in anticancer therapy, which
potentially can be overcome by local activation of a cytotoxic drug.
Such triggered activation can be obtained through modification of
a drug with a photoremovable protecting group (PPG), and subsequent
irradiation in the chosen place and time. Herein, the design, synthesis
and biological evaluation is described of a photoactivatable MDM2
inhibitor, PPG-idasanutlin, which exerts no functional effect on cellular
outgrowth, but allows for the selective, noninvasive activation of
antitumor properties upon irradiation visible light, demonstrating
activation with micrometer, single cell precision. The generality
of this method has been demonstrated by growth inhibition of multiple
cancer cell lines showing p53 stabilization and subsequent growth
inhibition effects upon irradiation. Light activation to regulate
protein–protein interactions between MDM2 and p53 offers exciting
opportunities to control a multitude of biological processes and has
the potential to circumvent common selectivity issues in antitumor
drug development.

Abstract
A series of benzimidazole-quinolone hybrids as new potential antimicrobial agents were designed and synthesized. Bioactive assays indicated that some of the prepared compounds exhibited potent antibacterial and antifungal activities. Notably, 2-fluorobenzyl derivative 5 b (ethyl 7-chloro-6-fluoro-1-[[1-[(2-fluorophenyl)methyl]benzimidazol-2-yl]methyl]-4-oxo-quinoline-3-carboxylate) showed remarkable antimicrobial activity against resistant Pseudomonas aeruginosa and Candida tropicalis isolated from infected patients. Active molecule 5 b could not only rapidly kill the tested strains, but also exhibit low toxicity toward Hep-2 cells. It was more difficult to trigger the development of bacterial resistance of P. aeruginosa against 5 b than that against norfloxacin. Molecular docking demonstrated that 5 b could effectively bind with topoisomerase IV-DNA complexes, and quantum chemical studies theoretically elucidated the good antimicrobial activity of compound 5 b. Preliminary experimental reaction mechanism exploration suggested that derivative 5 b could not intercalate into DNA isolated from drug-resistant P. aeruginosa, but was able to cleave DNA effectively, which might further block DNA replication to exert powerful bioactivities. In addition, compound 5 b is a promising antibacterial agent with membrane disruption abilities.

Abstract
Stimuli-responsive compounds that provide on-site, controlled antimicrobial activity promise an effective approach to prevent infections, reducing the need for systemic antibiotics. We present a novel pH-sensitive quaternary pyridinium salt (QPS), whose antibacterial activity is boosted by low pH and controlled by adjusting the pH between 4 and 8. Particularly, this compound selectively inhibits growth of acid-producing bacteria within a multispecies community. The successful antibacterial action of this QPS maintains the environmental pH above 5.5, a threshold pH, below which demineralization/erosion takes place. The design, synthesis, and characterization of this QPS and its short-chain analogue are discussed. In addition, their pH-sensitive physicochemical properties in aqueous and organic solutions are evaluated by UV-vis spectroscopy, dynamic light scattering, and NMR spectroscopy. Furthermore, the mechanism of action reveals a switchable assembly that is triggered by acid-base interaction and formed by tightly stacked π-conjugated systems and base moieties. Finally, a model is proposed to recognize the correlated but different mechanisms of pH sensitivity and acid-induced, pH-controlled antibacterial efficacy. We anticipate that successful application of these QPSs and their derivatives will provide protections against infection and erosion through targeted treatments to acid-producing bacteria and modulation of environmental pH.

Abstract
Biological processes are naturally regulated with high spatial and temporal control, as is perhaps most evident in metazoan embryogenesis. Chemical tools have been extensively utilized in cell and developmental biology to investigate cellular processes, and conditional control methods have expanded applications of these technologies toward resolving complex biological questions. Light represents an excellent external trigger since it can be controlled with very high spatial and temporal precision. To this end, several optically regulated tools have been developed and applied to living systems. In this review we discuss recent developments of optochemical tools, including small molecules, peptides, proteins, and nucleic acids that can be irreversibly or reversibly controlled through light irradiation, with a focus on applications in cells and animals.

Abstract
Owing to the dwindling arsenal of antibiotics, new methodologies for their effective and localized delivery are necessary. The use of optical control over delivery of drugs, also known as photopharmacology, has emerged as an important option for the spatiotemporally controlled generation of drugs and bioactive molecules. In the field of antimicrobial photopharmacology, most strategies utilize ultraviolet light for triggering release of the antibiotic. The use of such short wavelength light may have limitations such as phototoxicity. Here, a small molecule that is activated by visible light to release a fluoroquinolone, a broad-spectrum antibiotic, is reported. A boron-dipyrromethene, which is sensitive to cleavage at 470 nm, was used, and levofloxacin was used as a model fluoroquinolone. BDP-Levo was found to undergo cleavage in the presence of visible light to release the active antibiotic. Using growth inhibitory studies in Gram-positive as well as Gram-negative bacteria, the efficacy of BDP-Levo is demonstrated. Together, our study demonstrates that visible light can be used for optical control over antibiotic release and lays the foundation for visible-light-mediated antimicrobial photopharmacology.

Abstract
We describe a series of easily accessible, visible-light-sensitive (λ > 500 nm) BODIPY (boron-dipyrromethene)-based photoprotecting groups (PPGs) for primary and secondary amines, based on a carbamate linker. The caged compounds are stable under aqueous conditions for 24 h and can be efficiently uncaged in vitro with visible light (λ = 530 nm). These properties allow efficient photodeprotection of amines, rendering these novel PPGs potentially suitable for various applications, including the delivery of caged drugs and their remote activation.

Abstract
A general approach toward the light-induced guest release from cucurbit[7]uril by means of a photoactivatable competitor was devised. An o-nitrobenzyl-caged competitor is photolyzed to generate a competitive guest that can displace cargo from the host macrocycle solely based on considerations of chemical equilibrium. With this method the release of terpene guests from inclusion complexes with cucurbit[7]uril was demonstrated. The binding of the herein investigated terpenes, all being lead fragrant components in essential oils, has been characterized for the first time. They feature binding constants of up to 108 L mol-1 and a high differential binding selectivity (spanning four orders of magnitude for the binding constants for the particular set of terpenes). By fine-tuning the photoactivatable competitor guest, selective and also sequential release of the terpenes was achieved.

Abstract
We report the synthesis and photochemical properties of a series of dicyanocoumarinylmethyl (DEAdcCM)- and dicyanocoumarinylethyl (DEAdcCE)-based photocages of carboxylic acids and amines with absorption maximum around 500 nm. Photolysis studies with green light have demonstrated that the structure of the coumarin chromophore as well as the nature of the leaving group and the type of bond to be photocleaved (ester or carbamate) have a strong influence on the rate and efficiency of the uncaging process. These experimental observations were also supported by DFT calculations. Such differences in deprotection kinetics have been exploited to sequentially photolyze two dicyanocoumarin-caged model compounds (e.g., benzoic acid and ethylamine), and open the way to increasing the number of functional levels that can be addressed with light in a single system, particularly when combining dicyanocoumarin caging groups with other photocleavable protecting groups, which remain intact under green light irradiation.

Abstract
We report the design, synthesis, and spectroscopic characterization of a series of push-pull chromophores based on a novel coumarin scaffold in which the carbonyl of the lactone function of the original coumarin dyes has been replaced by the cyano(4-nitrophenyl)methylene moiety. The skeleton of the compounds was synthesized by condensation of a thiocoumarin precursor with the corresponding arylacetonitrile derivatives, and their photophysical properties were fine-tuned through the incorporation of electron-withdrawing groups (EWGs) like nitro and cyano at the phenyl ring, leading to absorption in the green to red region. Although fluorescence emission was weakened or even canceled upon introduction of two or three strong EWGs, the emission of the mononitro-containing coumarin derivatives in the red region upon excitation with green light is noticeable, as are their significantly large Stokes shifts. The new coumarin derivatives can be useful as photocleavable protecting groups, as demonstrated through the synthesis and characterization of a series of coumarin-based photocages of benzoic acid. Preliminary photolysis studies with green light have demonstrated that the structure of the coumarin chromophore influences the rate of the uncaging process, opening the way to exploiting these new coumarin scaffolds as caging groups that can be removed with visible light.

Abstract
Topology is a key element in structure-activity relationship estimation while designing physiologically-active molecular constructs. Peptides may be a preferred choice for therapeutics, principally due to their biocompatibility, low toxicity and predictable metabolism. Peptide design only guarantees functional group constitution by opting specific amino acid sequence, and not their spatial orientation to bind and incite physiological response on chosen targets. This is principally because peptide conformation is subject to external flux, due to the isotactic stereochemistry of the peptide chain. Stereochemical engineering of the peptide main chain offers the possibility of multiplying the structural space of a typical sequence to many orders of magnitude, and limiting the otherwise fluxional non-specific functional group dispensation in space by offering greater conformational rigidity. We put to test, this conceptual possibility already established in theoretical models, by designing amphipathic peptide systems and experimenting with them on Gram-positive, Gram-negative and antibiotic-resistant bacteria. The unusual conformational rigidity and stability of syndiotactic peptides enable them to retain the designed electrostatic environment, while they encounter the membrane surface. All the six designed systems exhibited bactericidal activity, pointing to the utility and specificity of stereo-engineered peptide systems for therapeutic applications. Overall, we hope that this work provides important insights and useful directives in designing novel peptide systems with antimicrobial activity, by expanding the design space, incorporating D-amino acid as an additional design variable.

Abstract
![]()
The use of coumarin
caged molecules has been well documented in
numerous photocaging applications including for the spatiotemporal
control of Cre-estrogen receptor (Cre-ERT2) recombinase activity.
In this article, we report that 4-hydroxytamoxifen (4OHT) caged with
coumarin via a conventional ether linkage led to
an unexpected photo-Claisen rearrangement which significantly competed
with the release of free 4OHT. The basis for this unwanted reaction
appears to be related to the coumarin structure and its radical-based
mechanism of uncaging, as it did not occur in ortho-nitrobenzyl (ONB) caged 4OHT that was otherwise linked in the same
manner. In an effort to perform design optimization, we introduced
a self-immolative linker longer than the ether linkage and identified
an optimal linker which allowed rapid 4OHT release by both single-photon
and two-photon absorption mechanisms. The ability of this construct
to actively control Cre-ERT2 mediated gene modifications was investigated
in mouse embryonic fibroblasts (MEFs) in which the expression of a
green fluorescent protein (GFP) reporter dependent gene recombination
was controlled by 4OHT release and measured by confocal fluorescence
microscopy and flow cytometry. In summary, we report the implications
of this photo-Claisen rearrangement in coumarin caged compounds and
demonstrate a rational linker strategy for addressing this unwanted
side reaction.
