Due to their unique pharmacol. characteristics, methylxanthines are known as therapeutic agents in a fascinating range of medicinal scopes. In this report, we aimed to examine some biol. effects of previously synthesized 8-alkylmercaptocaffeine derivatives Cytotoxic and antioxidative activity of 8-alkylmercaptocaffeine derivatives were measured in malignant A549, MCF7, and C152 cell lines. Assessment of cGMP levels and caspase-3 activity were carried out using a colorimetric competitive ELISA kit. Computational approaches were employed to discover the inhibitory mechanism of synthesized compounds Among the twelve synthesized derivatives, three compounds (C1, C5, and C7) bearing Pr, heptyl, and 3-methyl-Bu moieties showed higher and more desirable cytotoxic activity against all the studied cell lines (IC₅₀ < 100μM). Furthermore, C5 synergistically enhanced cisplatin-induced cytotoxicity in MCF-7 cells (CI < 1). Both C5 and C7 significantly increased caspase-3 activity and intracellular cGMP levels at specific time intervals in all studied cell lines (P < 0.05). However, these derivatives did not elevate LDH leakage (P > 0.05) and exhibited no marked ameliorating effects on oxidative damage (P > 0.05). Computational studies showed that H-bond formation between the nitrogen atom in pyrazolo[4,3-D] pyrimidine moiety with Gln817 and creating a hydrophobic cavity result in the stability of the alkyl group in the PDE5A active site. We found that synthesized 8-alkylmercaptocaffeine derivatives induced cell death in different cancer cells through the cGMP pathway. These findings will help us to get a deeper insight into the role of methylxanthines as useful alternatives to conventional cancer therapeutics.

Sarode, Bhagyesh R.;Kover, Karen;Friedman, Simon H. research published 《 Visible-Light-Activated High-Density Materials for Controlled in Vivo Insulin Release》, the research content is summarized as follows. In this work, we describe the synthesis, characterization, and ultimate in vivo assessment of second-generation insulin photoactivated depot (PAD) materials. These are the first to use visible light to stimulate insulin release and have an in vivo performance that is 28-fold improved relative to first-generation materials. This improvement is due to two major factors linked to the utilized chem.: (1) we have incorporated the coumarin photocleavable group, which increases the photorelease wavelength into the visible range, enhancing tissue penetration of the light; (2) phototoggling of insulin solubility is produced by linking three insulin mols. to a central bridge via light cleaved groups, and not by bonding to a large polymer. The resulting trimer is, therefore, highly dense (87% insulin dry weight/weight) but retains the insolubility required of the approach. Only after irradiation with visible light is native, soluble insulin is released from the dermal depot. This high d. increases the amount and ease of insulin release, as the d. of photolytic groups is 10-20-fold higher than in polymer-based first-generation materials. We have synthesized new azide-terminated coumarin linkers that we react with the amine groups of insulin. Using mass spectrometry methods, we identify the sites of reaction and purify individual isomers, which we demonstrate have in vitro photolysis rates that are within a factor of 2 of each other. We then reacted these terminal azide groups with a tridentate strained alkyne linker. We show that the resulting insulin trimer is highly insoluble, but can be milled into injectable particles that release insulin only in response to light from a 406 nm light source. Finally, we demonstrate that these materials have a significantly improved in vivo performance, releasing 28-fold more insulin on a per energy basis than first-generation materials.

Sato, Takeo;Shimada, Shigeru;Hata, Kazuo research published 《 Photo-aryl coupling and related reactions. II. Formation of triphenylenes from halo-o-terphenyls》, the research content is summarized as follows. Electronic effects on the photochem. conversion of o-terphenyl to triphenylene were examined by comparing the uv irradiation reaction, carried out in benzene using iodine as an oxidant, of three classes of o-terphenyl derivatives, 4- (I) and 4′-substituted (II) and 4,4”-disubstituted derivatives (III). While a strong electron-withdrawing group such as nitro group, hindered the cyclization reaction to occur, methoxy, fluoro, chloro and bromo compounds afforded the corresponding triphenylene derivatives With bromo and iodo compounds, however, a complex mixture of the products resulted due to photochem. cleavage of a carbon-halogen bonding, which led to the formation of phenylation products and hence phenyltriphenylenes together with reduction products. Further, with iodo compounds, it was found that no oxidant was necessary to effect the cyclodehydrogenation reaction since iodine was liberated during the photolysis. Possible pathways for the formation of the photolysis products from bromo and iodo compounds were discussed in relation to the relative rates of carbon-halogen cleavage and cyclization reactions. Comparison among three classes of halo compounds indicated that, with the exception of iodides, the cyclization reaction occurred more readily with type II compounds than type I compounds, while type III compounds reacted only with difficulty.
