Definitions
- the invention relates to a method for producing a coumarin-caged forskolin derivative, a corresponding forskolin derivative and the use of the forskolin derivative.
- Forskolin is a diterpene of the Labdan type from Coleus forskohlii (syn. Plectranthus barbatus), from the Lamiaceae family.
- Caged compounds are chemically modified compounds that release a defined substance when exposed to light of certain wavelengths. Its main area of application is biochemical and cell biological research. 1 ⁇ 2 biologically active compounds are equipped with a photolabile protective group ("cage") and are thus temporarily biologically inactive. The photolabile protective group is irreversibly split off by means of irradiation with light, and the previously inactive compound exhibits its specific biological activity again. Caged compounds are used to release effectors at a specific time at a specific location if their direct application is difficult or too slow to directly achieve the desired concentration at the location of action, e.g. B. inside a cell. The inactive caged connection can become on the other hand, enrich it at the target through slow diffusion and release a sufficient amount of effector in a short time with subsequent exposure.
- GPCR G-protein-coupled receptor
- Forskolin is used experimentally as a direct stimulator of adenylyl cyclases (ACs).
- ACs adenylyl cyclases
- Water-soluble forskolin derivatives such as. B. the commercially available Colforsin (NKH 477, see Figure 1, prior art), 6 are typically acylated at C-6 or C-7 with a polar aliphatic amine see. 7,8 These derivatives are usually even more selective for adenylyl cyclases and have lower off-target activities. 9
- the disadvantage is that there are no water-soluble forskolin derivatives that can be released under light control. There is therefore no “inactive” caged compound of forskolin that accumulates at the target through diffusion and targeted directly at the site of action through subsequent photolysis can be released in a very short time.
- the main difficulty is the complexity of a synthetic route.
- the object of the invention is to provide a method for producing “coumarin-caged forskolin derivatives”. Furthermore, it is an object of the invention to provide the corresponding cuma rin-caged forskolin derivatives in order to be able to carry out cell- or tissue-based examinations with them.

- a mild catalyst such as. B. NaHS0 4 * SiC> 2 in a non-polar aprotic solvent such as CH2Cl2, benzene, ether and so on and between about 10 ° C to 30 ° C.
- the coumarin-caged forskolin derivative is used
- a first carbamoylation of a (pseudo) halogen-substituted, protected coumarin is carried out (analogous to FIG. 3), in order to insert an N-methylalkylenediamine function there.
- a nitrophenyl carbonate of the protected, (pseudo) halogen-substituted 4-hydroxymethylcoumarin 6 or its analogs is reacted with trifluoro-N- (2- (methylamino) alkyl) acetamide 5 or its analogs.
- the trifluoroacetyl group is then split off (first deprotection, analogous to FIG. 4).
- the amine 3 (or its analogues) formed in this way is coupled to the completely protected forskolin carbonate 2 in the next step by a second carbamoylation (analogous to FIG. 5).
- the coupled product 7 (or its analogues) is acetylated on forskolin (acetylation analogous to FIG. 6) and completely deprotected in two further steps to form caged forskolin JCF 1 or its analogues (second and third deprotection, analogous to FIGS. 7 and 8 ).
- Step a. of claim 1 then reads for the general synthesis method: 2,2,2-trifluoro-N- (2-methylamino- G
- JCF 1 (or its analogues provided according to the invention) is cleaved after irradiation with light in a photolysis to forskolin- (2- (methylamino) ethyl) carbamate 10 (or its homologues), CO2 and the corresponding methyl coumarin derivative (FIG. 9) .
- the other coumarin-caged forskolin derivatives according to the invention are cleaved analogously to the homologous forskolin carbamates, CO 2 and the corresponding methyl coumarin derivatives.
- the coumarin-caged forskolin derivative can advantageously be introduced into a cell and, after the irradiation, the increase in the intracellular cAMP concentration, which occurs due to the binding of the biologically active forskolin carbamate 10 to membrane-bound adenylyl cyclases endogenously in the cells, measured using a fluorescence-based sensitive detection method becomes.

- FIG. 15 Relative fluorescence without loading (negative control); the times were measured at intervals of 1 min.
- Figure 1 shows the prior art, forskolin and NKH 477.
- JCF 1 as a coumarin-caged forskolin derivative is synthesized in a 6-step synthesis starting from protected forskolin 2 and a coumarin derivative 3 functionalized with N-methylethylenediamine (FIG. 2).
- the six synthesis stages (FIG. 3 to FIG. 8) and the synthesis products mentioned therein with the reference numerals 1, 3, 4, 7, 8, 9 are not previously known from the literature. Their overall yield is 5% based on the carbonate 6.
- JCF 1 (or its analogues) can be split under irradiation with light to give the desired forskolin carbamate 10 (FIG. 9 and FIG. 10) and thus qualifies for the biological application mentioned above.
- JCF 1 The photolysis of JCF 1 is carried out under controlled conditions in order to quantitatively demonstrate the release of forskolin carbamate 10 as a function of the amount of light absorbed: 0.16 ml of a 100 mM solution of JCF 1 in MeOH are placed in a quartz glass cuvette (width: 4 mm; depth (optical path): 10 mm -> filling height 4 mm) given.
- the "Intensilight” light source excitation lamp of a Nikon TI Eclipse fluorescence microscope
- the excitation source the light of which passes through a gel light guide (active diameter: 4 mm) and a narrow band pass filter (368.8 nm ⁇ 5 nm) onto the liquid column in the cuvette is directed.
- the irradiated samples are then mass spectrometrically (mass spectrometer: MSQ Plus from ThermoScientific; ionization: ESI interface with a cone voltage of 50 V, eluent: methanol, water, glacial acetic acid, / 50, 50, 0.02 / vol, vol, vol ; Flow rate 0.2 ml / min; direct injections of 20 m ⁇ of the respective irradiated samples via a Rheodyne injection valve (7725i)).
- the mass trace m / z 51 1 and the mass range m / z 807-811 are recorded.
- the integrals of the peaks of the chromatogram of the mass trace m / z 51 1 are evaluated (see FIG. 10). With an exposure time of 320 seconds, no more signals can be detected in the mass range m / z 807-811 (starting compound), so that, under the conditions described above, complete conversion can be assumed after this time.
- reaction can also be carried out in an analogous manner with the analogs of JCF-1 provided according to the invention.
- the influx of Ca 2+ can be detected with Ca 2+ -sensitive dyes or genetically-coded Ca 2+ indicators, such as GCaMP sensors, in a fluorescence reader or with a fluorescence microscope.
- Ca 2+ -sensitive dyes or genetically-coded Ca 2+ indicators such as GCaMP sensors
- GCaMP sensors genetically-coded Ca 2+ indicators
- a cell line which, in addition to the above-mentioned CNG channel, also constitutively expresses the genetically encoded Ca 2+ indicator GCaMP3.0 (Tian et al., 2009).
- the GCaMP3.0 protein consists of a circularly permuted EGFP (Enhanced Green Fluorescent Protein), at the N-terminal a binding peptide for calmodulin from the myosin light Chain kinase (Ml 3 peptide) and C-terminal of a calmodulin are fused.
- EGFP Enhanced Green Fluorescent Protein
- Ml 3 peptide myosin light Chain kinase
- C-terminal of a calmodulin are fused.
- GCaMP3.0 does not emit fluorescence at low intracellular Ca 2+ concentrations. When the intracellular Ca 2+ concentration increases, Ca 2+ ions bind to the calmodulin. This then interacts with the M13 peptide and a conformational change of the total protein results.
- GCaMP3.0 fluoresces after exposure to a wavelength of 480 nm at 510 nm. The Ca 2+ -dependent change in the fluorescence change can be recorded and quantified
- the use of the JCF 1 is universally suitable for all cell- and tissue-based samples in which the intracellular cAMP concentration should be increased.
- the possibility of activating the biologically active compound at defined times and within the cell, for example by local release by means of punctiform exposure, has great advantages over conventional strategies in which an increase in the intracellular cAMP concentration, e.g. via GPCR signaling pathways, via the stimulation of the adenylyl cyclases eg NKH 477, or the inhibition of the cell's own phosphodiesterases, which hydrolyze the cAMP to AMP, eg by IBMX. With the latter method, there are always changes in the cAMP concentration in the entire cell or within the cell or tissue association.
- the use of the biologically inactive compound 1 also enables the kinetics of cellular processes, which are controlled by increasing the intracellular cAMP concentration, to be recorded with a high time resolution in the sub-second range.
