A series of pyrrolopyrrole aza boron dipyrromethene derivatives have been designed and synthesised as two-photon fluorescent probes. The bisalkynyl analogues, having a donor-π-donor quadrupolar skeleton, show a red-shifted Q band at ca. 700 nm in toluene and a two-photon absorption (TPA) cross-section up to 2349 GM at 1040 nm. To enable these dyes to be used for subcellular imaging, a branched oligoethylene glycol unit has been introduced to enhance their hydrophilicity and biocompatibility, and a potential organelle-selective group, namely triphenylphosphonium or morpholine moiety has also been added with a view to targeting the mitochondria or lysosomes respectively. The resulting conjugates are essentially non-aggregated in deionised water, exhibiting an intense Q band at 668 nm and a TPA cross-section up to 384 GM at 1040 nm. These spectral features have been analysed using density functional theory calculations, which suggest that the TPA is mainly due to the S0 → S2 transition. In the subcellular imaging study, it has been found that the triphenylphosphonium-containing derivative can localise in the lysosomes of HeLa human cervical carcinoma cells, which may be a result of its positive charge and the negative logP value (-2.46, P = partition coefficient), while the morpholine-substituted analogue does not exhibit preferential subcellular localisation.
GLP-1 RECEPTOR MODULATORS

Paragraph 00507, (2016/06/28)
Compounds are provided that modulate the glucagon-like peptide 1 (GLP-1) receptor, as well as methods of their synthesis, and methods of their therapeutic and/or prophylactic use. Such compounds can act as modulators or potentiators of GLP-1 receptor on their own, or with incretin peptides such as GLP-1(7-36) and GLP-1(9-36), or with peptide-based therapies, such as exenatide and liraglutide, and have the following general structure (where "^^^^" represents either or both the R and S form of the compound) (I) where A, B, C, Y1, Y2, Z, R1, R2, R3, R4, R5, W1, n, p and q are as defined herein.

, p. 85 - 94 (2007/10/02)
Homologues series of some derivatives of 3,5-(4-substituted phenyl)-1,2,4-oxydiazole were synthesized and their phase behavior studied.Introduction of the pentagonal heteroaromatic ring leads to significant changes in mesomorphic behavior in comparison with analogous compounds containing the phenyl ring.The synthesised compounds exhibit smectic and nematic phases. - Keywords: 1,2,4-oxadiazole, nematic and smectic liquid crystals
