1 Q: “The main purpose of the
2 survey is to help in establishing the
3 basic relationship between organosilicon
4 structure and biological activity, the
5 further pursuit of which rests with our
6 secondary stage research activity into the
7 physiology (metabolism, mechanism of
8 action, site of action, et cetera) of the
9 compounds in a good screening procedure
10 for identification of developmental
11 potential. The microorganisms used in the
12 survey were specifically chosen (in
13 addition to their representativeness) for
14 their further usefulness in the secondary
15 stage of research. A great deal of
16 background information on the biochemistry
17 of these organisms is available”
18 What this suggests is that Dr.
19 Isquith’s work was really part of a larger
20 project; that although he was looking at
21 antimicrobials, his work was useful in
22 the—total mission of Bioscience,
23 and I was wondering if that corresponds
24 with your—Did that correspond with your
25 view back in 1969?

3 The witness
4 That corresponds with my view.
5 EXAMINATION BY MR. ELLIS
6 Q. And what was it about the
7 ability of certain organosilicon compounds
8 to have antimicrobial effect that had some
9 implications in the—in the larger
10 scheme of things concerning biological
11 activity
12 A. That has to be a technical
13 answer.
14 Q. Okay. Not what I like, but if
15 that’s the only way we can do it
16 A. Well, then maybe I didn’t
17 understand what you want.
18 Q. What was it about—He was
19 Doing very of specific work; correct”
20 A. Yes.
21 Q. He was looking at the ability
22 of certain organosilicon compounds to kill
23 viruses or to kill bacteria.
24 A. (Witness nods head
25 affirmatively.)
Page 385
1 Q. What implications did that
2 work have in the broader mission of
3 Bioscience in terms of biological
4 activity?
5 A. If you knew that they killed
6 microbes, then you have—you will always
7 have a suspicion that they kill other
8 cells potentially, not necessarily true
9 but potentially.
10 Q. Okay
11 A. And that includes any kind of
12 cell, because that’s what bacteria
13 and viruses are.
14 Q. Including—
15 Mr. DONLEY:
16 Any kind of what?
17 Mr. ELLIS
18 Cell.
19 THE WITNESS
20 Cell.
21 EXAMINATION BY MR. ELLIS:
22 Q. Including potentially cells in
23 the human body?
24 A. Any cell.
25 Q. And one type of antiviral drug
Page 386
1 that was being looked is was what I think
2 Dr. Lake or Dr. Isquith called chemo
3 chemotherapeutic, which is the ability of
4 an antiviral drug to actually kill the
5 virus.
6 A. Chemotherapy, description of
7 It is—Yes—is to either inhibit the
8 growth of or to kill microbes.
9 Q. And were you thinking in 1969
10 that this work potentially, not, obviously
11 immediately, but potentially, you know
12 five, six, seven, eight years down the
13 line could eventually lead to the
14 development of a drug that possibly could
15 be used for an antiviral—
16 A. Definitely.
17 Q --for an anticancer drug—
18 A. Definitely.
19 Q. --or a drug that possibly
20 Could be used to treat autoimmune disease?
21 MR. DONLEY
22 Objection. Leading.

24 No
