NPC

This indicator is particularly useful where investment capital is a main constraint, it is a measure of capital efficiency, sometimes referred to as NPV/NPC. 

In addition to halopeiidol, the putative neuroleptics, limcazole (311), lemoxipiide (312), and gevotioline (313) bind to (7-ieceptois as does the dopamine uptake blocker, GBR 12909 (314) and two ligands active at the NMDA receptor, ifenprodil (315) and CNS 1102 (316). NPC 16377, (317) is a selective (7-teceptor ligand. MAO inhibitors and antidepressants also bind to (7-teceptors. Some evidence indicates that (7-teceptors in the brain are in fact a form of cytochrome which may account for the diversity of ligands interacting with (7-sites.

These macromolecules include histones, ribosomal proteins and ribosomal subunits, ttansctiption factors, and mRNA molecules. The transport is bidirectional and occurs through the nucleat pote complexes (NPCs). These are complex stmctures with a mass approximately 30 times that of a ribosome and are composed of about 100 diffetent proteins. The diameter of an NPC is approximately 9 run but can increase up to ap-ptoximately 28 nm. Molecules smaller than about 40 kDa can pass through the channel of the NPC by diffusion, but special translocation mechanisms exist fot latget molecules. These mechanisms are under intensive investigation, but some important features have already emerged.

The TLC process is an off-line process. A number of samples are chromatographed simultaneously, side-by-side. HPTLC is fast (5 min), allows simultaneous separation and can be carried out with the same carrier materials as HPLC. Silica gel and chemically bonded silica gel sorbents are used predominantly in HPTLC other stationary phases are cellulose-based [393]. Separation mechanisms are either NPC (normal-phase chromatography), RPC (reversed-phase chromatography) or IEC (ion-exchange chromatography). RPC on hydrophobic layers is not as widely used in TLC as it is in column chromatography. The resolution capabilities of TLC using silica gel absorbent as compared to C S reversed-phase absorbent have been compared for 18 commercially available plasticisers, and 52 amine and 36 phenolic AOs [394]. 

The first pyrrolylphosphazenes were apparently prepared by McBee and coworkers in 1960, and although the work was never documented in the chemical literature, hexakis-(pyrrolyl)cyclotriphosphazene (1) and octakis-(pyrrolyl)cyclotetraphosphazene were described in a Technical Report of the Defense Technical Information Center.19 Compound 1 was reported to be produced in 26% yield from the interaction of hexachlorocyclotriphosphazene [(NPC 2)3] with excess potassium pyrrolide in refluxing benzene over a 24 hour period. Lithium pyrrolide and pyrrolyl magnesium bromide were found to be unsatisfactory reagents for the preparation of 1. 

The yield of the potassium pyrrolide reaction is considerably improved by the use of a phase transfer catalyst.20 However, in exploratory work on this substitution reaction we have found that sodium pyrrolide reacts with (NPC 2)3 in tetrahydrofuran at room temperature to produce 1 in quantitative yield in less than 3 hours. The structure of the compound20 is reproduced in Figure 1. 

Nevertheless, through scrupulous purification of the reaction components and rigorous control of the reaction conditions it is possible to isolate the polymer in a state of good purity, by the reaction of potassium pyrrolide with (NPC 2)x in tetrahydrofuran at room temperature (Equation l). Addition of water to the reaction mixture precipitates the polymer as a white rubbery solid which hardens on drying. A 3IP NMR spectrum of a typical reaction product is given in Figure 2.
