A series of new N -acylsubstituted thioureas, the compositions and structures of which were determined by IR and PMR spectroscopy and mass spectrometry, were synthesized from the alkaloid anabasine. The crystal structure of one of the products, N -(anabasino-1-thiocarbonyl)furan-2-carboxamide, was confirmed by x-ray structure analysis. It was also shown that this compound exhibited moderate antibacterial activity.

Coaxing a Pyridine Nucleus To Give Up Its Aromaticity: Synthesis and Pharmacological Characterization of Novel Conformationally Restricted Analogues o

A series of novel nicotine and anabasine related conformationally restricted compounds including those with pi-bonds in the connecting tether were synthesized following the hitherto unprecedented phenylsulfanyl group assisted generation of pyridine o-quinodimethane intermediates and their trapping by an intramolecular Diels-Alder reaction. Pharmacological characterization of some of these analogues at activating alpha3beta4 nAChRs was investigated, and constrained anabasine analogues 35 and 43 as well as constrained nicotine analogue 42 were found to exhibit moderately potent nicotinic agonist activity. Of special note is the fact that the pyrrolidinic nitrogen in these compounds is bound to a carbomethoxy group and, therefore, is not free to be protonated unlike all the known analogues of nicotine and anabasine, specifically designed as nAChRs agonists/antagonists. The structure-activity relationship studies indicate that when pi-cation interaction is absent, the position of chlorine atom in the pyridine ring and steric bulk at the connecting tether between the pyridine and pyrrolidine ring of the constrained nicotinic ligands are important descriptors for their binding affinity at alpha4beta2 and alpha3beta4 nAChRs as well as the subtype selectivity issue. These findings are likely to improve our understanding of the structural requirements for selectivity, which, at present, is probably the most important goal in the field of nicotinic ligands.

Culture an Inescapable Thing

People are what their culture makes them. It brings people together or separate them, through heritage. As it is our interaction with the world; influenced through our childhood and heritage. Culture is the most influential element in society, it impacts the way a person views their surroundings, affecting their morals, values, and decisions.

Culture becomes our guidelines sometimes blinding us. A person acts the way they do, because they were raised that way. This is especial true in Robert Lake's letter "An Indian father's plea". In the letter he informs his son's teacher how his classmates are treating him due to him being cultural different. The classmates act in this way due to their culture, and the values they have inheritance from their ancestors. These values are racist and judgmental, for example "He ask why one young white girl at school who is his friend tells him, "I like you, Wind-Wolf, because you are a good Indian." This shows that his classmate's culture is infused with judgment of others based on the color of their skin. Similar Pico Iyer's essay "where worlds collide" shows another case where cultural views are clouding one's judgement. "Yes on proposition 187. Mexicans go home" (Iyer 51), shows a negative view of Mexicans, as proposition 187 issued in 1994 stated that no alien make receive public benefits. This shows how American people wanted to separate Mexicans from Americans, this issue resulted from cultural differences.

Culture stays with one's self throughout their life. People don't leave their comfort zone, as such they don't abandon their traditions and morals that were passed down to them. One stays true to one's culture, this is especial expressed in "everyday use" by Alice Walker. The story is about mother and her two daughters, Maggie and Dee. The idea of heritage is show through the quilts, as the central argument is over the cultural values of the quilts. "I can 'member grandma Dee without the quilts"(Walker 65). This quote shows that Maggie has no need for a physical manifest of her culture unlike Dee; she can remember with the values and lessons she was taught.

Culture doesn't influence a person's decisions, and confuses them, the best example of this would be Dee in "Everyday use". She couldn't stand her culture as she was embarrassed by it, to the point that she once wrote to her mother "that no matter, where you live I will come see, but I won't bring my friends" (Walker 60). She left in order to find a better "culture", one that was completely different from her mother's and Maggie's. In my opinion the idea that Dee was not confused about her culture is untrue. Dee changes her name to better suite her African heritage, later she comes home with a false sense of heritage. She asks for the quilts so she can hang them in a museum like exhibit style, this suggests that she feels reverence for them but that to her they are essentially foreign, impersonal objects. She doesn't understand the true value of them as they were made from old clothes used by her ancestors meant for everyday use. She has created a false cultural identity as she doesn't understand her true heritage is the one of her Mother and not her African heritage.

One way or other cultural will somehow influence a, throughout their life, it might cloud their judgment. Culture often makes people biased on a certain topic, sometimes turning into pure racism as with Mexicans in "where worlds collide". A person stays true to the ideas and values that is their culture as with Maggie, who unlike Dee didn't try to create a false heritage. Culture is an inescapable thing that will always be the basics for all decisions that a person will ever make.

Influence of nicotine, cotinine, anabasine and cigarette smoke extract on human granulosa cell progesterone and estradiol synthesis

Influence of nicotine, cotinine, anabasine and cigarette smoke extract on human granulosa cell progesterone and estradiol synthesis.

P M Gocze, I Szabo, D A Freeman

Abstract

To reveal the well known effect of smoking on the incidence of early abortion, the possible effects of cigarette alkaloids on progesterone and estradiol synthesis were investigated. A suspected cause for early spontaneous abortion is corpus luteum insufficiency. The present experiments evaluate the effects of cigarette smoke alkaloids on progesterone and estradiol biosynthesis. Human granulosa cells were obtained from patients undergoing in vitro fertilization and embryo transfer treatment because of infertility. Incubation of the granulosa cells with cotinine, anabasine, with the combination of nicotine, cotinine and anabasine, or with an aqueous extract of cigarette smoke resulted in inhibition of progesterone synthesis. The alkaloids and smoke extract decreased the DNA content of the culture dish. These latter findings suggested a cytotoxic effect of the alkaloids. Both cotinine and anabasine slightly stimulated the synthesis of normalized estradiol. However, nicotine, combination of all three alkaloids, and cigarette smoke extract had no significant influence on estradiol production. Taken together, these data would suggest that cigarette alkaloids inhibit cellular progesterone synthesis both by inhibiting progesterone synthesis and by causing less specific toxic effects to the cell. In contrast, cigarette smoke alkaloids slightly stimulated or had no effect on estradiol production. These concomitant actions of cigarette alkaloids partly explain the higher incidence of early abortion in pregnant women who smoke.
