Acta Pharm. 48 (1998) p. I

Erratum

In the issue No. 1, Vol. 48 (1998), in the article MINDO/III and graph theoretical study of nicotinic acid/amide and their positional isomers written by Arabinda Ray and Gunamani Deheri the following errors occurred:
    The text on page 16:
"two molecules in each series. This is true for PY^*CONCH₃ and PY^*COOCH₃ derivatives but not for PY^*CON(CH₃)₂.
    It has been already discussed in the preceding section that for biological activity the nicotinic acid/amide has to be attached to the dinucleotide."
    should be replaced with:
    "It was therefore deemed proper to investigate what happens in the minimal distance D, between the different positional isomers, if the dinucleotide is replaced by H⁺ as this can easily attack the N of the ring. Consequently, the minimal distance D was calculated for the different positional isomers, viz. Nicotinic-picolinic, Nicotinic-isonicotinic acid/amide."
    The paragraph:
    "Indeed, the orthogonal path descriptors and the related aspects incorporated in this paper have been due to him."
    on page 18 should be omitted.
