cf. CA 56, 15544b; 58, 1333a; 59, 13792b. The relation of the Taft substituent constant (Σσ^*) is linear with respect to log K^20°_association and the shift of the OH stretching vibration fundamental (Δv_OH) for 22 organophosphorus compounds in mixed solutions with phenol, ethanol, and α-naphthol in CCl₄. Σσ^* is also linear with respect to log K^20°_association for the organophosphorus compounds with iodine in CCl₄ solution, and with the wavelength shift of the visible absorption band of iodine from near 518 mμ. The relation between Σσ^* and P:O stretching frequencies in cm.^-1 (v_PO) is not linear for these organophosphorus compounds in CCl₄ solution, contrary to previous reports (Griffin, CA 55, 1415h). However, some of G.’s determinations of v_PO were on pure films, and these compounds are associated in the pure state.

Gramstad, Thor published the artcileStudies of hydrogen bonding. Part XXXIII. Dipole moments of phosphoryl compounds and their hydrogen-bonded complexes with phenol, Application In Synthesis of 866-23-9, the publication is Acta Chemica Scandinavica (1992), 46(11), 1087-91, database is CAplus.

The dipole moments of 33 phosphoryl compounds and of their hydrogen-bonded complexes with phenol have been determined in CCl₄ at 20°. In general there is no correlation between the dipole moments and the O-H stretching frequency shift accompanying the complexation of phenol with the phosphoryl compounds A smooth correlation is observed, however, for some series of closely related phosphoryl compounds The influence of the various substituents on the dipole moment is discussed. The vectorially calculated dipole moments of the complexes were smaller than the corresponding dipole moments obtained exptl. The vectorial difference, Δμ, is greatest for phosphoryl compounds containing the N-P:O and C₆H₅-P:O groups.

Griffin, C. E. published the artcilePhosphoryl stretching frequency correlation for phosphonic acid derivatives, Computed Properties of 866-23-9, the publication is Chemistry & Industry (London, United Kingdom) (1960), 1058-9, database is CAplus.

A plot of Σ σ* (Taft substituent constants) vs. γ_PO (as films in CS₂ or CCl₄) for 19 phosphonates [RP(O)XY] (I) gave a linear relationship; a least squares treatment of the data gave γ_PO = 16.80 Σσ* + 1198. The following I were studied (X = Y = OEt) (R given): Me, Et, Pr, Bu, n-C₆H₁₃, CH₂:CH, CH₂:CHCH₂, PhCH₂, Ph, ClCH₂, Cl₂CH, CCl₃ (II), BrCH₂, HOCH₂, AcCH₂. Also I (R, X, and Y given): Me, OMe, OMe; Me, OEt, NMe₂; Me, NMe₂, NMe₂ (III); Ph, H, OEt. The average deviation between calculated and observed frequencies was ±4 cm.^-1; the only significant deviation occurred with II and III, and may have arisen through disturbance of the normal inductive effects of the substituents by field effects. Major deviations from the linear relationship also occurred with frequency values obtained in the presence of H-bonding solvents. The following σ* values were tentatively assigned: (CH₂)₂CO₂Et, 0.39; (CH₂)₃CO₂Et, 0.39; NEt₂, 0.68.

CCl₄ and (EtO)₃P at 80° give 80-5% Cl₃CP(O)(OEt)₂ (I). The reaction is inhibited by hydroquinone but traces of Bz₂O₂ give a 4-fold increase in reaction rate (89% yield at 80°). Irradiation of the reaction mixture at room temperature with a Hanovia ultraviolet lamp gives 80% I; under similar conditions BrCCl₃ and (EtO)₃P give 88% I. No reaction is observed in the dark at room temperature (30 days). These results confirm the chain process proposed by Kamai and Kharrasova (C.A. 52, 3666a).

Herbain, Maurice published the artcileA biologic test of antilipemic heparin derivatives, Recommanded Product: 3-Carboxy-N,N,N-trimethylpropan-1-aminium chloride, the publication is Clinica Chimica Acta (1960), 204-7, database is CAplus and MEDLINE.

cf. Velluz, et al., CA 53, 10555g, 19898g. Rabbits were fed a diet containing saturated fats and 200 mg./kg./day cholesterol for a period of 30 days. Those animals in which serum total cholesterol levels reached 8 g./l. or more were selected for testing. The ratio of β-lipoprotein lipide/total lipide exceeded 0.70 compared to a control value of 0.35. After removal of cholesterol from the diet for 24 hrs., 5 mg./kg. heparin or other antilipemic agent was injected intravenously and total and β-lipoprotein lipides (the latter were precipitated with dextran) were estimated at 6, 10, and 14 hrs. When the test was carried out with N-dimethylbenzoyl-N-desulfoheparin, its antilipemic activity was found to be slower but more intense than that of heparin.

Ribonucleosides were phosphorylated selectively, to give the 2′-phosphate derivative, with Et trichloromethylphosphonate (I) when the ribonucleoside contained the cis-2′,3′-diol group. Treatment of uridine (over-night) with I in HCONMe2 containing Et3N gave 67% of the corresponding uridine nucleotide. Similarly prepared were the nucleotides of cytidine, adenosine, and 6-azauridine in 23, 45, and 3% yield, resp. Thymidine and 2′,3′-O-isopropylideneuridine did not give the nucleotides as they could not form a cyclic intermediate. -(α-L-Lyxofuranosyl)adenine, in which two cyclic intermediates were conformationally allowed, gave 95% of a nucleotide mixture containing 2- and 3-isomeric phosphates and the 3,5-cyclic phosphate in 23, 37, and 35% yield, resp.

Ren, Jing-Ling published the artcileLimonoids containing a C₁-O-C₂₉ moiety: isolation, structural modification, and antiviral activity, Quality Control of 6313-54-8, the publication is Marine Drugs (2018), 16(11), 434, database is CAplus and MEDLINE.

Five new limonoids named thaigranatins A-E (1-5), containing a C1-O-C29 moiety, were isolated from seeds of the Thai Xylocarpus granatum, collected at the mangrove swamp of Trang Province, together with the known limonoid, granatumin L (6). The structures of these compounds were established by HR-ESIMS and extensive NMR spectroscopic data. The absolute configuration of 1 was unequivocally determined by single-crystal X-ray diffraction anal., conducted with Cu Kα radiation; whereas that of 2 or 6 was established to be the same as that of 1 by the similarity of their electronic CD (ECD) spectra. In view of the marked antiviral activity of 6, its structure was modified via hydrolysis with alk. KOH, esterification with diazomethane and various organic acids, and oximization with hydroxyamine. Finally, 18 derivatives, viz. 7-10, 8a-8i, 9a-9b, and 10a-10c, were obtained. In vitro antiviral activities of these derivatives against human immunodeficiency virus 1 (HIV-1) and influenza A virus (IAV) were evaluated. Most notably, 8i exhibited marked inhibitory activity against HIV-1 with an IC50 value of 15.98 ± 6.87 μM and a CC50 value greater than 100.0 μM; whereas 10b showed significant inhibitory activity against IAV with an IC50 value of 14.02 ± 3.54 μM and a CC50 value greater than 100.0 μM.
