1 so to speak, to help your group develop
2 some of these products?
3 A. Since I don’t remember that
4 specifically, I’m—I have to assume it
5 was—it was done by someone else, but I
6 could be wrong. It was someone higher
7 corporation in executive management,
8 perhaps Dr. Hunter, perhaps Dr. Bass,
9 whoever.
10 Q. Okay. Well, let’s turn to the
11 actual meeting that you had with Lepetit
12 in January 1971—
13 A. Okay.
14 Q. --and it appears that you had
15 met with a Dr. Lerner there, who was an
16 endocrinologist. And I’m on page 5464
17 A. Yes
18 Q. Does that appear to be
19 accurate?
20 A. Uh-huh (indicating
21 affirmatively).
22 Q. Okay. Now, again, an
23 endocrinologist is somebody who looks at
24 the endocrine system which included—
25 includes the reproductive system; correct?
Page 432
1 A. Correct.
2 Q. And you had been looking at
3 the reproductive system at least for the
4 effects of 2,6 cis and some other
5 organosilicon compounds; correct?
6 A. Right.
7 Q. Okay. And, indeed, you had
8 found that 2,6 cis had some effect on—I
9 believe you were studying the male
10 reproductive system, or was it the female?
11 A. Both. It was an estrogen-like
12 substance, and therefore, it was both.
13 Q. Okay. An estrogen-like
14 substance; what does that mean in simple
15 terms?
16 A. It had hormonal activity and
17 had the effects of an estrogen as well as
18 an anti-estrogen agent. It had both
19 effects. It just simply mimicked the
20 action of estrogen as a hormonal in the
21 body and was an anti-estrogen as well.
22 Q. It had both types of effects?
23 A. Yes. That is common among
24 drugs to have agonist activity like and
25 antagonist opposing activity within the
1 same molecule. Many examples of that.
2 Q. Okay. Is that similar to how
3 the same compound could in some ways
4 suppress after an immune suppressant and
5 then at the same time act as—to
6 activate the immune system?

10 Q. Is that a similar type of
11 concept?
12 A. It’s—It’s an analogy. I’m
13 trying to think of one, and I can’t for
14 specifically immune system as such.
15 Q. The reason I made that
16 reference is later we’re going to come to
17 a document that talks about some types of
18 0rganosilicon compounds at the same time
19 acting as a suppressant for the immune
20 system and also activating the immune
21 system
22 MR. DONLEY
23 Objection. That’s not a
24 Question.

1 Q. But you had found—in any
2 event, you had found both types of
3 estrogen-like activity and
4 anti-estrogen-like activity with 2,6 cis?
5 A. I believe it’s principally
6 classified as anti-estrogen.
7 Q. Okay. Now by 1972 when you
8 made this visit to Lepetit had you also
9 done some work on the effect of 2,6 cis on
10 the central nervous system?
11 A. Yes
12 Q. And what were—
13 A. 2,6 cis on the central nervous
14 system, I have to ask for a clarification.
15 Hormones—The major
16 pituitary glad is considered to be a—
17 if you will, a part of the endocrine
18 system, but it’s in the brain. And if
19 you’re talking about the mechanism of
20 action studies that were conducted on the
21 central nervous system to determine if
22 that where the site of action of 2,6 cis
23 was, yes, those kinds of studies were—
24 were done.
25 Q. And actually, you have found
