Abstract
Photopharmacology can be implemented in a way of regulating drug activities by light-controlling the molecular configuations. Three photochromic ligands (PCLs) that bind on one or two sites of GABARs and nAChRs were reported here. These multiphoton PCLs, including FIP-AB-FIP, IMI-AB-FIP, and IMI-AB-IMI, are constructed with an azobenzene (AB) bridge that covalently connects two fipronil (FIP) and imidacloprid (IMI) molecules. Interestingly, the three PCLs as well as FIP and IMI showed great insecticidal activities against Aedes albopictus larvae and Aphis craccivora. IMI-AB-FIP in both trans/cis isomers can be reversibly interconverted depending on light, accompanied by insecticidal activity decrease or increase by 1.5-2.3 folds. In addition, IMI-AB-FIP displayed synergistic effects against A. craccivora (LC50, IMI-AB-FIP = 14.84-22.10 μM, LC50, IMI-AB-IMI = 210.52-266.63 μM, LC50, and FIP-AB-FIP = 36.25-51.04 μM), mainly resulting from a conceivable reason for simultaneous targeting on both GABARs and nAChRs. Furthermore, modulations of wiggler-swimming behaviors and cockroach neuron function were conducted and the results indirectly demonstrated the ligand-receptor interactions. In other words, real-time regulations of receptors and insect behaviors can be spatiotemporally achieved by our two-photon PCLs using light.

Abstract

Photopharmacology
uses light to regulate the biological activity
of drugs. This precise control is obtained through the incorporation
of molecular photoswitches into bioactive molecules. A major challenge
for photopharmacology is the rational design of photoswitchable drugs
that show light-induced activation. Computer-aided drug design is
an attractive approach toward more effective, targeted design. Herein,
we critically evaluated different structure-based approaches for photopharmacology
with Escherichia coli dihydrofolate reductase (eDHFR)
as a case study. Through the iterative examination of our hypotheses,
we progressively tuned the design of azobenzene-based, photoswitchable
eDHFR inhibitors in five design–make–switch–test–analyze
cycles. Targeting a hydrophobic subpocket of the enzyme and a specific
salt bridge only with the thermally metastable cis-isomer emerged as the most promising design strategy. We identified
three inhibitors that could be activated upon irradiation and reached
potencies in the low-nanomolar range. Above all, this systematic study
provided valuable insights for future endeavors toward rational photopharmacology.

Abstract
Naturally occurring avermectins are allosteric modulators of glutamate-gated chloride channels (GluCls) and possess exceptionally potent anthelmintic, acaricidal, and insecticidal activities. Here, we develop photoswitchable azobenzene-avermectin (ABAVM) derivatives, which can be photoactivated upon ultraviolet irradiation. After illumination, the best compound p-AB4″AVM had a 1.88-fold and 2.74-fold insecticidal activity enhancement toward Culex pipiens pallens and Mythimna separata larvae, respectively. p-AB4″AVM allows for optical regulation of dorsal unpaired median neuron membrane potential with a 2.15-fold fluorescence intensity decrease after illumination. p-AB4″AVM and p-AB5AVM enable optical modulation of the behavioral response of Culex pipiens pallens larvae with 1- and 4-fold reduced mobility upon irradiation, respectively. The ABAVMs could be used to reversibly manipulate GluCls with light and may be useful for the mechanistic study of macrocyclic lactone insecticides.

Abstract
The optical control and investigation of neuronal activity can be achieved and carried out with photoswitchable ligands. Such compounds are designed in a modular fashion, combining a known ligand of the target protein and a photochromic group, as well as an additional electrophilic group for tethered ligands. Such a design strategy can be optimized by including structural data. In addition to experimental structures, computational methods (such as homology modeling, molecular docking, molecular dynamics and enhanced sampling techniques) can provide structural insights to guide photoswitch design and to understand the observed light-regulated effects. This review discusses the application of such structure-based computational methods to photoswitchable ligands targeting voltage- and ligand-gated ion channels. Structural mapping may help identify residues near the ligand binding pocket amenable for mutagenesis and covalent attachment. Modeling of the target protein in a complex with the photoswitchable ligand can shed light on the different activities of the two photoswitch isomers and the effect of site-directed mutations on photoswitch binding, as well as ion channel subtype selectivity. The examples presented here show how the integration of computational modeling with experimental data can greatly facilitate photoswitchable ligand design and optimization. Recent advances in structural biology, both experimental and computational, are expected to further strengthen this rational photopharmacology approach.

Abstract
![]()
Photopharmacology addresses the challenge of drug selectivity and
side effects through creation of photoresponsive molecules activated
with light with high spatiotemporal precision. This is achieved through
incorporation of molecular photoswitches and photocages into the pharmacophore.
However, the structural basis for the light-induced modulation of
inhibitory potency in general is still missing, which poses a major
design challenge for this emerging field of research. Here we solved
crystal structures of the glutamate transporter homologue GltTk in complex with photoresponsive transport inhibitors—azobenzene
derivative of TBOA (both in trans and cis configuration) and with the photocaged compound ONB-hydroxyaspartate.
The essential role of glutamate transporters in the functioning of
the central nervous system renders them potential therapeutic targets
in the treatment of neurodegenerative diseases. The obtained structures
provide a clear structural insight into the origins of photocontrol
in photopharmacology and lay the foundation for application of photocontrolled
ligands to study the transporter dynamics by using time-resolved X-ray
crystallography.

Abstract
Photoresponsive ligands are powerful tool compounds for studying receptor function with spatiotemporal resolution. However, to the best of our knowledge, such a ligand is not available for the ryanodine receptor (RyR). Herein, we present a photochromic ligand (PCL) for insect RyR by decorating chlorantraniliprole (CHL) with photoswitchable azobenzene (AB). We demonstrated that one potent ligand, named ABCHL13, shows light-induced reversible trans-cis isomerization and 3.5-fold insecticidal activity decrease toward oriental armyworm (Mythimna separata) after UV-light irradiation, that is, trans-ABCH13 has higher activity than the cis-ABCH13. ABCHL13 enables optical control over intracellular Ca2+ release in dorsal unpaired median (DUM) neurons of M. separata and American cockroach (Periplaneta americana) and cardiac function of P. americana. Our results provide a first photopharmacological toolkit that is applicable to light-dependent regulation of RyR and heart beating.

Abstract
Photopharmacology offers facile solutions for spatiotemporal control over ligand activity and receptor function. The meta-diamide insecticide acts on insect GABA receptors (GABARs) as an antagonist that causes firing of a neuron. We present here photochromic GABAR ligands azobenzene-meta-diamides (ABMDAs) by incorporating photoswitchable azobenzene with meta-diamides. ABMDAs showed good isomerization efficiency and fatigue resistance. Among them, ABMDA7 shows a 1.5-fold insecticidal activity difference towards mosquito larvae (Aedes albopictus) before and after UV illumination. We translated this light-dependent activity difference to the optical modulation of the membrane potential of American cockroach (Periptaneta americana) DUM neurons. This light-responsive meta-diamide-based GABAR ligand allows for optical regulation of insecticidal activity and DUM neurons.

Abstract
Three dinuclear metal complexes (comprised of six-coordinated nNi2L and five-coordinated nCu2L and nZn2L) were confirmed by means of elemental analysis, UV-vis and IR spectra, and single X-ray crystal structural analysis in a spectroscopic study. The stable structures of these nNi2L, nCu2L, and nZn2L complexes in poly(vinylalcohol) (PVA) films were analyzed using UV-vis spectra. The molecular orientation of hybrid PVA film materials after linearly polarized light irradiation was analyzed to obtain the polarized spectra and dichroic ratio. Among the three materials, nNi2L and nZn2L complexes indicated an increasing optical anisotropy that depended on the flexibility of the complexes. We have included a discussion on the formation of the pseudo-crystallographic symmetry of the components in a soft matter (PVA films).

Abstract
Benzoylphenylureas (BPUs) are used as synthetic insect growth regulators for inhibiting chitin synthesis. Merging insecticidal BPUs with photoswitchable azobenzene generated photoresponsive chitin synthesis inhibitors. A prepared azobenzene-benzoylphenylurea can be activated upon irradiation with UV light, and shows 6-fold and 2-fold activity difference to armyworm (Mythimna separata) and German cockroach (Blattella germanica) sulfonylurea receptors, respectively. This is the first example of a photoswitchable BPU insecticide. The generation of such a photoresponsive BPU insecticide allows for modulation of the insecticidal activity by light, and may facilitate the spatiotemporal control over the sulfonylurea receptor and the mechanistic study of this kind of insecticide.
