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
A number of p-pyridinyl oxime carbamate derivatives were prepared upon the reaction of the corresponding oximes with isocyanates. These novel compounds reacted photochemically in the presence of supercoiled plasmid DNA. Structure-activity relationship (SAR) studies revealed that the substituent on the imine group was not affecting the extend of the DNA damage, whereas the substituent of the carbamate group was critical, with the halogenated derivatives to be able to cause extensive single and double stranded DNA cleavages, acting as "synthetic nucleases", independently of oxygen and pH. Calf thymus-DNA affinity studies showed a good-to-excellent affinity of selected both active and non-active derivatives. Preliminary theoretical studies were performed, in an effort to explain the reasons why some derivatives cause photocleavage and some others not, which were experimentally verified using triplet state activators and quenchers. These theoretical studies seem to allow the prediction of the activity of derivatives able to pass intersystem crossing to their triplet energy state and thus create radicals able to damage DNA. With this study, it is shown that oxime carbamate derivatives have the potential to act as novel effective photobase generating DNA-photocleavers, and are proposed as new leads for "on demand" biotechnological applications in drug discovery and medicine.

Abstract
As a contribution to the development of novel coumarin-oxime ether conjugates with therapeutically interesting properties, a series of coumarin-oxime ether (1a-1j) was synthesised using SN2 reaction of bromomethyl coumarins with butane-2,3-dione monoxime. Invitro anti-tuberculosis activityagainstMTBH37Rv strain was established for the coumarin-oxime ether (1a-1j). Most of the compounds exhibited significant activity with minimum inhibitory concentration (MIC)in the range of 0.04-3.12 μg mL-1. Compound (1h) was identified as a hit candidate exhibiting MIC of 0.04 μg mL-1, closer to the MIC value of Isoniazid (0.02 μg mL-1), a commercially available drug for the treatment of tuberculosis. Compound 1h also displayed a low level of toxicity in Vero cells along with a good safety profile in vitro. Compounds that showed potent anti-tubercular activity were also found to cleave DNA more efficiently and thereby exhibit nuclease activity. The most active compound (1h) was further studied to deduce the mode of interaction with model serum protein, bovine serum albumin (BSA).

Pyridine and p-Nitrophenyl Oxime Esters with Possible Photochemotherapeutic Activity: Synthesis, DNA Photocleavage and DNA Binding Studies. Molecules 2016; 21:molecules21070864.

Abstract
Compared to standard treatments for various diseases, photochemotherapy and photo-dynamic therapy are less invasive approaches, in which DNA photocleavers represent promising tools for novel “on demand” chemotherapeutics. A series of p-nitrobenzoyl and p-pyridoyl ester conjugated aldoximes, amidoximes and ethanone oximes were subjected to UV irradiation at 312 nm with supercoiled circular plasmid DNA. The compounds which possessed appropriate properties were additionally subjected to UVA irradiation at 365 nm. The ability of most of the compounds to photocleave DNA was high at 312 nm, whereas higher concentrations were required at 365 nm as a result of their lower UV absorption. The affinity of selected compounds to calf-thymus (CT) DNA was studied by UV spectroscopy, viscosity experiments and competitive studies with ethidium bromide (EB) revealing that all compounds interacted with CT DNA. The fluorescence emission spectra of the pre-treated EB-DNA exhibited a moderate to significant quenching in the presence of the compounds indicating the binding of the compounds to CT DNA via intercalation as concluded also by DNA-viscosity experiments. For the oxime esters the DNA photocleavage and affinity studies aimed to clarify the role of the oxime nature (aldoxime, ketoxime, amidoxime) and the role of the pyridine and p-nitrophenyl moieties both as oxime substituents and ester conjugates.

Abstract
![]()
We
report a switchable redox click and cleave reaction strategy for conjugating
and releasing a range of molecules on demand. This chemoselective
redox-responsive ligation (CRRL) and release strategy is based on
a redox switchable oxime linkage that is controlled by mild chemical
or electrochemical redox signals and can be performed at physiological
conditions without the use of a catalyst. Both conjugation and release
reactions are kinetically well behaved and quantitative. The CRRL
strategy is synthetically modular and easily monitored and characterized
by routine analytical techniques. We demonstrate how the CRRL strategy
can be used for the dynamic generation of cyclic peptides and the
ligation of two different peptides that are stable but can be selectively
cleaved upon changes in the redox environment. We also demonstrate
a new redox based delivery of cargoes to live cells strategy via the
CRRL methodology by synthesizing a FRET redox-responsive probe that
is selectively activated within a cellular environment. We believe
the ease of the CRRL strategy should find wide use in a range of applications
in biology, tissue engineering, nanoscience, synthetic chemistry,
and material science and will expand the suite of current conjugation
and release strategies.

Abstract
Photolytic cleavage of the nitrogen-nitrogen single bond in benzaldehyde phenylhydrazones produced aminyl (R2N*) and iminyl (R2C=N*) radicals. This photochemical property was utilized in the development of hydrazones as photo-induced DNA-cleaving agents. Irradiation with 350 nm UV light of arylhydrazones bearing substituents of various types in a phosphate buffer solution containing the supercoiled circular phiX174 RFI DNA at pH 6.0 resulted in single-strand cleavage of DNA. Attachment of the electron-donating OMe group to arylhydrazones increased their DNA-cleaving activity. Results from systematic studies indicate that both the aminyl and the iminyl radicals possessed DNA-cleaving ability.
