Abstract

The program uses the joint Monte Carlo-Simplex algorithm for fitting the generalized, non-monoexponential model of externally detected decay of radiotracer activity in the tissue. The optimal values of the model parameters (together with the rate of the blood flow) are calculated. A table and plot of the experimental points and the fitted curve are generated. The program was written in Borland's Turbo Pascal 5.5 for the IBM PC XT/AT and compatible microcomputers.

A novel workflow for the inverse QSPR problem using multiobjective optimization.

A workflow for the inverse quantitative structure-property relationship (QSPR) problem is reported in this paper for the de novo design of novel chemical entities (NCE) in silico through the application of existing QSPR models to calculate multiple objectives, including prediction confidence measures, to be optimized during the de novo design process. Two physical property datasets are applied as case studies of the inverse QSPR workflow (IQW): mean molecular polarizability and aqueous solubility. The case studies demonstrate the optimization of molecular structures to within a property range of interest; the optimized structures are then validated against QSPR models that are generated from sets of alternative descriptors to those used in the IQW. The paper concludes with a discussion of the results from the case studies.

Quantitative structure-property relationships for direct photolysis of polybrominated diphenyl ethers.

Using semiempirical quantum chemical descriptors, by partial least squares (PLS) regression, quantitative structure-property relationships (QSPRs) were established for direct photolysis quantum yields (Phi) and rate constants (k) of polybrominated diphenyl ether congeners dissolved in water/methanol and methanol solutions, respectively, and irradiated by artificial ultraviolet A light. Q(cum)(2), a parameter indicating robustness and predictive abilities of PLS models, for the significant QSPR models is larger than 0.702. The gap of frontier molecular orbital energies (E(LUMO)-E(HOMO)) and the most positive Mulliken atomic charges on a hydrogen atom (q(H+)) are two main molecular structural factors governing the logPhi values. logPhi increases with increasing E(LUMO)-E(HOMO) and q(H+) values. logk is mainly related to bromination degree and pattern which can be characterized by molecular weight (Mw), average molecular polarizability (alpha), and average Mulliken atomic charges on bromine atoms (q(Br)). logk increases with bromination degree (Mw, alpha) and q(Br).
