inositol polyphosphates are useful tools for biological studies. Racemic 2,3,6-tri-O-butyryl-myo-inositol 1,4,5-trisphosphate hexakis(acetoxymethyl) ester(), myo-inositol 1,4,5-trisphosphate hexakis(acetoxymethyl) ester (), hexakis(propionyloxymethyl) ester () and hexakis(butyryloxymethyl) ester () were therefore synthesized. Whereas extracellular application of up to 200 μM of or to 1321N1 astrocytoma

Inositol phosphates, as important second messengers of signal transduction, regulate many biological functions. However, cell penetration and phospholipase stability could be two main issues faced by inositol phosphate analogues used as lead compounds for drug discovery. Inositol phosphotriester analogues could be more beneficial to diffuse across plasma membrane. In this paper, we describe the design and synthesis of a series of inositol phosphotriester analogues based on phosphatidylinositol, along with the initial antitumor activity analysis. Several compounds exhibited good cytotoxic activity against human cancer cell lines A549, HepG2, MDA-MB-231 and HeLa, especially compound 33 was cytotoxic against all the four cancer cell lines with good IC50 values.

Proposed structures of pinpollitol, namely 1,4-di-O-methyl-chiro-inositol and 1,3-di-O-methyl-chiro-inositol, have been synthesized from myo-inositol. Racemic 1,4-di-O-methyl-chiro-inositol has been synthesized from the readily available l,2:4,5-di-O-isopropylidene-myo-inositol, in five steps while DL-1,3-di-O-methyl-chiro-inositol from myo-inositol 1,3,5-orthoformate in nine steps. A comparison of
An efficient routefrom myo- to neo-inositol is described. The key steps of the sequence are oxidation of the hydroxy group at C-5 to the corresponding ketone, followed by a highly (dr = 7.8:1) stereoselective reduction. The route includes nine steps with an overall yield of 51% and is therefore superior to all hitherto reported methods for the preparation of neo-inositol.
Total synthesis of new 1,5-bissubstituted myo-inositol derivatives. Synthesis of D-myo-inositol 1,5-bisphosphate, 3,5-bisphosphate and of rac. 1,5-Bissulphated and 1,5-bissulphamoylated isosteric analogues
